v0.2.2

Changes

• Keep the bottom sheet tab bar in sync with the active sheet — The tab bar now scrolls to keep the current sheet visible when switching with [ / ].

• New tests — 2 new regression tests for tab bar clipping and active-sheet tracking (70 total).

• New tests — 7 new tests for date/timestamp conversion
• Code quality — Fixed clippy lints, formatted with cargo fmt

v0.2.0

New features:

• Large file support for CSV: byte-offset index enables instant opening and smooth scrolling for files of any size. Only the visible viewport is loaded into memory.
• Large file support for Parquet: row-group-level lazy loading with targeted row selection. Jumping to any row (gg/G) is nearly instant regardless of file size.
• CSV/Parquet files now use lazy backends; Excel remains fully in-memory (no streaming API in calamine).

Internal changes:

• Introduce RowBackend enum (InMemory / Csv / Parquet) for polymorphic row storage
• Replace direct .rows access with get_row() / prefetch_range() API
• 61 tests pass (all 55 original + 6 new)
