* Add Kiro provider and transparent auto-model naming
- Add Kiro IDE provider: parses .chat JSON files, estimates tokens,
normalizes dot-versioned model IDs for cost lookup
- Show "Cursor (auto)", "Copilot (auto)", "Kiro (auto)" in CLI
dashboard instead of pretending to know which model was used
- Route auto model names through BUILTIN_ALIASES for cost estimation
* Fix menubar tabs: add missing providers, show period-scoped costs
- Add Kiro, OMP to ProviderFilter enum so installed providers appear as tabs
- Merge Cursor + Cursor Agent into single Cursor tab
- Tab costs now reflect the selected period (7d/30d/month/all) instead
of always showing today
- Tab visibility still uses today's provider list so tabs don't
disappear when switching to periods with no data
* Add accent color picker to menubar with Apple system presets
- 9 presets using Apple's exact macOS dark-mode accent colors
(Ember, Blue, Purple, Pink, Red, Orange, Yellow, Green, Graphite)
- Color picker in header, persisted via UserDefaults
- "Burn" text stays fixed ember regardless of accent
- ThemeState is MainActor-isolated for thread safety
- Picker state lifted to AppStore so it survives .id() tree rebuild
- Accessibility labels on all color swatches
- Renamed brandAccentDark/brandEmberDeep/brandEmberGlow to match
their actual light/deep/glow semantics
* Fix review findings: case-sensitive cost lookup, Kiro timestamp guard, cache versioning
- Normalize provider dictionary keys to lowercase in tab cost lookup
so "Cursor Agent" (title-case from CLI) matches providerKeys
- Guard against missing/invalid/epoch startTime in Kiro parser to
prevent RangeError crash or 1970-01-01 ghost entries
- Bump DAILY_CACHE_VERSION to 4 so upgraded users get a clean
recompute with the new auto-model naming (cursor-auto vs default)
- Add version field to cursor-results.json cache to invalidate stale
entries that still use the old 'default' model name
