TaskNotes 4.3.20 (Fork)

This release is from the cybersader/tasknotes fork.

NotificationCache: High-performance caching layer for notification items
- 45-second TTL on aggregated results
- In-flight promise deduplication (prevents concurrent duplicate evaluations)
- Folder→Bases inverted index for O(1) invalidation lookup
- Bell click is now instant (~1ms cache hit vs ~200-500ms full scan)
Per-category reminder behavior settings: Each time category has configurable behavior
- Overdue, today, tomorrow, thisWeek, scheduled, queryBased categories
- Dismiss behaviors: until-restart, snooze-1h/4h/1d, until-data-change, until-complete, permanent
- Per-category bell toggle (show/hide in status bar count)
- Per-category toast toggle (show/hide popup notification)
- Advanced settings section in Settings → Notifications → General
Scrollable toast items: Click "+X more" to enable scroll mode with all items visible
Ctrl+hover page preview: Task titles in toast support Ctrl+hover to show page preview

Bell shows PENDING only: Status bar count now shows only unseen items where category has showInBellCount: true
Smart invalidation: File changes only re-evaluate bases that monitor the changed folder (not ALL bases)
Console log timestamps: All debug console output now includes ISO timestamps for traceability
Settings reorganized: Notifications section split into General/Task/Base sub-sections
- Global settings (toast click, status bar click, check interval, show on startup) moved to General
- Per-category behavior settings in General → "Reminder behavior by category (advanced)"

Toast click area: Click handler now includes subtitle text for expand mode (was only handling explicit elements)
Constant background activity: Removed O(n) "evaluate ALL bases" approach on every file change
Delayed bell response: Bell click now returns cached data instantly instead of waiting for full evaluation
