Update README.md

Adds build, install, and uninstall targets with standard PREFIX/DESTDIR
support. Installs binary, desktop file, metainfo, GSettings schema,
app icons, scalable action icons (outlay + tabler), and bundled fonts.
This allows distro packagers (Nix, Arch, Debian, etc.) to properly
install icons alongside the binary so GTK can find them at runtime.

+# Feature Batch 2 Design - 16 Features
+
+Date: 2026-03-03
+
+## Overview
+
+16 features sourced from Reddit community research on personal finance app wishlists, filtered against Outlay's existing feature set.
+
+## Features
+
+### 5. Custom Budget Cycle
+
+Users can choose how budget periods are defined:
+
+- **Calendar month** (default, current behavior): 1st to last day of month
+- **Payday offset**: budget runs from day X to day X-1 of next month (e.g. 15th to 14th)
+- **Rolling N-day**: budget period is a fixed window of N days from a configurable start date
+
+New settings: `budget_cycle_mode` (calendar/payday/rolling), `budget_cycle_start_day` (1-31), `budget_cycle_days` (e.g. 30).
+
+Affects: Budgets view period labels ("Mar 15 - Apr 14"), navigation step size, all budget queries, safe-to-spend calculation, and budget threshold notifications. Charts and History remain calendar-month based to avoid confusion.
+
+Cycle configuration accessible via a gear icon popover next to the month nav in Budgets view.
+
+### 6. Bulk Transaction Operations
+
+Selection mode in History view:
+
+- "Select" button in header bar activates selection mode
+- Checkboxes appear on each transaction row
+- Long-press also enters selection mode
+- Action bar: "Delete (N)", "Recategorize", "Tag", "Select All", "Cancel"
+- Delete shows confirmation dialog with count
+- Recategorize opens a category picker, applies to all selected
+- Tag opens a multi-select tag picker, applies to all selected
+
+### 7. Monthly/Yearly Recap
+
+Part of the new Insights view (see below). Toggle between "This Month" and "This Year".
+
+Monthly recap: total income, expenses, net, transaction count. Per-category rows showing amount, percentage of total, and change vs previous month with directional arrows.
+
+Yearly recap: month-by-month summary with sparklines, year-over-year comparison.
+
+"Share as PDF" button reuses existing PDF export.
+
+### 8. Natural Language Entry
+
+Dedicated smart entry bar at the top of Log view and in Quick Add popup.
+
+`adw::EntryRow` titled "Quick entry" with placeholder "e.g. Coffee 4.50 at Starbucks".
+
+Parser (`outlay-core/src/nlp.rs`):
+- `parse_transaction(input, categories) -> Option<ParsedTransaction>`
+- Extracts amount (required), category (fuzzy match), note, payee (after "at"/"from"/"to")
+- Patterns: "Coffee 4.50", "Lunch 12.50 at Subway", "4.50 groceries milk", "$25 gas"
+
+Preview row shows parsed result below the entry. Press Enter to save. Existing detailed form remains below for manual entry.
+
+### 9. Sankey Diagram
+
+New section in Charts view after existing charts. Title: "Money Flow".
+
+Cairo-drawn Sankey layout:
+- Left nodes: income categories
+- Right nodes: expense categories
+- Center node: "Available" (net)
+- Flow widths proportional to amounts
+- Income flows colored green, expense flows use category colors
+- Hover shows amount labels
+
+Layout computation in `outlay-core/src/sankey.rs`:
+- `compute_sankey_layout(income_sources, expense_categories) -> SankeyLayout`
+- Returns node positions and bezier curve control points
+
+Month navigation synced with other charts.
+
+### 10. What-If / Sandbox Mode
+
+Toggle button in Budgets view header bar.
+
+When active:
+- Header tinted amber, label shows "Sandbox Mode"
+- All budget amounts become inline-editable
+- Changes stored in temporary `HashMap<i64, f64>`, NOT written to DB
+- Progress bars and safe-to-spend recalculate live
+- Modified rows get a visual indicator
+- "Apply Changes" button writes sandbox values to DB
+- "Discard" button exits sandbox, reverts to real data
+
+### 11. Tags UI
+
+Database tables already exist (`tags`, `transaction_tags`). Need GTK surfaces:
+
+- History view: tag chips in FlowBox alongside category chips (different visual style - outlined vs filled). Clicking a tag chip filters to transactions with that tag.
+- Log view: tags already have an entry field. Ensure it works with `get_or_create_tag()` and `set_transaction_tags()`.
+- Edit dialog: show and edit tags on existing transactions.
+- Bulk operations: "Tag" action in selection mode.
+
+### 12. Transaction Splits UI
+
+Database tables already exist (`transaction_splits`). Need GTK surfaces:
+
+- Log view / Edit dialog: "Split" toggle button next to category row
+- When enabled: category row replaced by split list
+- Each split row: category dropdown + amount entry + optional note
+- "Add Split" button for more rows
+- Validation: split total must equal transaction amount ("Remaining: X.XX" label)
+- On save: `insert_splits()` called after transaction insert
+- Edit dialog: if `has_splits()`, pre-fills split rows
+
+### 13. Transaction Templates UI
+
+Database tables already exist (`transaction_templates`). Need GTK surfaces:
+
+- Log view: "Templates" icon button in header opens a popover
+- Lists saved templates as `adw::ActionRow` items (name, amount, category icon, type badge)
+- Tapping a template fills the log form
+- "Save as Template" button at bottom of form when amount + category are filled
+- Opens dialog for template name, saves via `insert_template()`
+
+### 14. Auto-Categorization Rules UI
+
+Database tables already exist (`categorization_rules`). Need GTK surface in Settings:
+
+- New "Categorization Rules" `adw::PreferencesGroup` between Categories and Import/Export
+- Each rule: `adw::ActionRow` showing field (Note/Payee), pattern, target category
+- "Add Rule" button opens dialog: field dropdown, pattern entry, category dropdown, priority spinner
+- Delete button per row
+- Rules applied during import and optionally during manual entry
+
+### 15. Searchable Category Picker
+
+Replace all `adw::ComboRow` category dropdowns with a searchable version:
+
+- Custom `gtk::FilterListModel` backed by `gtk::StringFilter`
+- Search entry at top of dropdown popup
+- Typing filters category list in real-time
+- Shared utility: `fn make_searchable_category_combo(...) -> adw::ComboRow`
+- Used in: log view, edit dialog, budget dialog, quick add, split rows, rules dialog
+
+### 16. PDF Bank Statement Import
+
+New "PDF" import button in Settings alongside existing importers.
+
+Two-phase extraction (`outlay-core/src/import_pdf.rs`):
+1. Text extraction via `pdf-extract` crate - look for tabular date/description/amount patterns
+2. If no extractable text found, fall back to existing Tesseract OCR pipeline
+
+Preview dialog shows extracted transactions in an editable list. Each row: date, description, amount, category (auto-matched via categorization rules, fallback "Uncategorized"). Import All / Import Selected buttons. Merge/replace mode toggle.
+
+New dependency: `pdf-extract` crate.
+
+### 17. Spending Streaks / Gamification
+
+Dedicated Insights view (new sidebar item) with three sections:
+
+**Streaks:**
+- No-spend streak: consecutive days with zero expenses, flame icon, "Best: X days"
+- Under-budget streak: consecutive months staying under total budget cap
+- Savings streak: consecutive months with goal contributions
+
+**Achievements:**
+- Grid of achievement badges, earned ones colored, unearned dimmed
+- Starter set: "First Transaction", "7-Day No-Spend", "30-Day No-Spend", "Month Under Budget", "3 Months Under Budget", "First Goal Completed", "100 Transactions", "Budget Streak 6mo"
+- Checked and awarded on app launch
+
+New tables: `streaks`, `achievements`.
+
+### 18. Financial Goal Projections
+
+Enhance existing Goals view:
+
+- Each active goal row gets subtitle: "At current rate, reachable by [date]"
+- Based on average monthly contributions over last 3 months
+- States: "On track - X months ahead", "Behind schedule - need X.XX/month", "Start contributing to see projection"
+- Expandable section per goal: mini line chart showing saved amount over time with projected line to target
+
+### 19. Credit Card Billing Cycle Tracking
+
+Dedicated Credit Cards view (new sidebar item).
+
+**Summary card:** total balance, total limit, utilization bar, next due date.
+
+**Card list:** each card is `adw::ExpanderRow`:
+- Collapsed: name, balance, due countdown, utilization mini-bar
+- Expanded: statement close date, minimum payment, payment history (last 3 months)
+- Actions: "Record Payment" (creates expense transaction, reduces balance), Edit, Delete
+
+New table: `credit_cards` (name, credit_limit, statement_close_day, due_day, min_payment_pct, current_balance, currency, color, active).
+
+### 24. Spending Anomaly Alerts in UI
+
+Surface existing `detect_anomalies()` in two places:
+
+- **History view:** `adw::Banner` at top when anomalies exist for the displayed month: "N spending insights for this month". Tapping navigates to Insights view.
+- **Insights view:** Anomaly Alerts section renders each anomaly as `adw::ActionRow` with warning/info icons. Clickable to navigate to category in History.
+- **Startup:** toast on first launch of the day if current month has insights.
+
+## Schema Migration (v8 -> v9)
+
+New table: `credit_cards` - see feature #19 above.
+New table: `streaks` - see feature #17 above.
+New table: `achievements` - see feature #17 above.
+New settings: `budget_cycle_mode`, `budget_cycle_start_day`, `budget_cycle_days`.
