- Fix hook dependency issues in AbacusVisionBridge by using destructured
stable function references instead of remoteCamera object
- Add proper container dimension tracking for remote camera calibration
overlay to fix coordinate mismatch
- Add rotate180 option to perspectiveTransform to support both Desk View
(camera pointing down, needs 180° rotation) and phone cameras (no rotation)
- Phone camera cropping now uses direct mapping without rotation
The main issues fixed:
1. Hook dependencies were causing effects to run repeatedly when navigating
to remote camera URL in a different window
2. CalibrationOverlay was using hardcoded fallback dimensions instead of
actual container dimensions for remote camera
3. Perspective transform was applying 180° rotation which is wrong for
phone cameras held at normal angles

Major changes:
1. Sentinel approach for skill recency refresh
- Added 'recency-refresh' session status and SlotResult source field
- BKT skips pKnown updates for sentinel records (zero-weight)
- refreshSkillRecency() now inserts sentinel records instead of updating DB field
- Single source of truth: all lastPracticedAt comes from problem history
2. Skill progress chart (new component)
- 100% stacked area chart showing skill distribution over time
- Clickable legend cards for filtering by classification
- Adaptive time window presets (Recent, Last N, All)
- Synthetic "current" snapshot ensures chart matches legend staleness
3. Trend-aware encouragement messages
- Linear regression to detect improving/declining/stable trends
- Session timing analysis (gap detection, frequency patterns)
- Window-aware scope text ("over the past 2 weeks", "since Nov 15")
- Priority-based message selection (urgent issues first)
- Consistent "stale" terminology (not "rusty")
4. Dashboard improvements
- Virtualized session history list for performance
- Paginated session history API with cursor-based pagination
- BKT-computed lastPracticedAt used throughout (single source of truth)

The codebase previously used "help level" terminology (HelpLevel type,
helpLevelUsed field, helpLevelWeight function) which implied a graduated
scale. Since the system now only tracks whether help was used or not,
this renames everything to use proper boolean terminology.
Changes:
- Delete HelpLevel type, use boolean directly
- Rename helpLevelUsed → hadHelp in SlotResult
- Rename lastHelpLevel → lastHadHelp in PlayerSkillMastery schema
- Rename helpLevelWeight() → helpWeight() with boolean parameter
- Update all components, tests, stories, and documentation
- Add database migration for column rename

- Add bottomOffset/rightOffset to MyAbacusContext for virtual keyboard avoidance
- NumericKeypad sets offsets when mounted (48px bottom, 100px right)
- Floating abacus repositions above/beside keyboard in portrait/landscape
- PracticeSubNav: fix horizontal overflow with minWidth: 0 on flex children
- SessionProgressIndicator: allow proper flex shrinking
- ActiveSession: reduce padding/gaps, use flex layout to fill available space
- PracticeClient: use fixed positioning with proper insets for all orientations
- Portrait: bottom 48px for keypad
- Landscape: right 100px for keypad
- Desktop: no offsets needed
- Prevent viewport scrolling during practice sessions
