Clean up low-severity code quality issues

Browse Source 
- Share IMAGE_EXTENSIONS between discovery.rs and watcher.rs (DRY)
- Extract compute_renamed_path() to deduplicate ~100 lines in executor
- Extract estimate_text_dimensions() to deduplicate watermark calc (3 copies)
- Fix encoder fallback defaults: WebP 85, AVIF 63 (match QualityPreset::High)
- Extract watch_config_dir() and load_watches() helpers in CLI (4 copies)
- Remove redundant else branches after unwrap_or_default()
- Rename misleading chrono_timestamp() to unix_timestamp()
