Major new version (#2)

Release Notes

Architecture
- Component refactor: removed monoliths (`Calendar.vue`, `CalendarGrid.vue`); expanded granular view + header/control components.
- Dialog system introduced (`BaseDialog`, `SettingsDialog`).

State & Data
- Store redesigned: Map-based events + recurrence map; mutation counters.
- Local persistence + undo/redo history (custom plugins).

Date & Holidays
- Migrated all date logic to `date-fns` (+ tz).
- Added national holiday support (toggle + loading utilities).

Recurrence & Events
- Consolidated recurrence handling; fixes for monthly edge days (29–31), annual, multi‑day, and complex weekly repeats.
- Reliable splitting/moving/resizing/deletion of repeating and multi‑day events.

Interaction & UX
- Double‑tap to create events; improved drag (multi‑day + position retention).
- Scroll & inertial/momentum navigation; year change via numeric scroller.
- Movable event dialog; live settings application.

Performance
- Progressive / virtual week rendering, reduced off‑screen buffer.
- Targeted repaint strategy; minimized full re-renders.

Plugins Added
- History, undo normalization, persistence, scroll manager, virtual weeks.

Styling & Layout
- Responsive + compact layout refinements; header restructured.
- Simplified visual elements (removed dots/overflow text); holiday styling adjustments.

Reliability / Fixes
- Numerous recurrence, deletion, orientation/rotation, and event indexing corrections.
- Cross-browser fallback (Firefox week info).

Dependencies Added
- date-fns, date-fns-tz, date-holidays, pinia-plugin-persistedstate.

Net Change
- 28 files modified; ~4.4K insertions / ~2.2K deletions (major refactor + feature set).
