Release 0.4.14 — Performance, Security & Platform Hardening

Major release bringing near-instantaneous menubar dropdown animations, native macOS system menu integration (PlatformMenuBar), destructive query confirmation modals, deep memory optimizations (string interning, compact column vectors), complete data grid keyboard navigation, and rich multi-format cell inspection.

---

✨ Highlights

⚡ Instantaneous Menubar Dropdowns & Titlebar Polish (#672, #673)

• Accelerated dropdown open animation to 60ms with Curves.easeOutCubic.
• Eliminated initial pointer-down delay by triggering top-level menus on mouse down (onTapDown).
• Unwrapped Menubar from MoveWindow to prevent OS window drag gesture competition from delaying menu clicks.
• Unified TapRegion boundaries and enabled clean toggle-close and zero-latency sibling menu switching.

🛡️ Destructive Query Confirmation Modal (#608, #622, #638, #641)

• Safety confirmation modal for destructive DDL and DML operations (DROP, TRUNCATE, bulk DELETE/UPDATE without WHERE).
• Visual SQL diff preview, detected operations list, and mandatory acknowledgement checkbox before execution across core and extension workspaces.

⌨️ Data Grid Keyboard Navigation & Rich Cell Inspector (#662, #663, #664, #665)

• Full arrow-key navigation across virtual grid cells with Tab/Shift+Tab traversal, Enter to commit, and Escape to cancel.
• Multi-format modal cell inspector supporting raw Text, formatted JSON, XML/HTML, and Hex/Binary with word-wrap toggle.
• Added full Binary / BLOB data support in DML staging and generation (X'...', \x...) (feat(workspace): support binary and BLOB data types in DML mutation engine and grid validator #658, feat(workspace): support binary and BLOB data types in DML mutation engine and grid validator #661).

🍎 Native macOS PlatformMenuBar Integration (#612, #626)

• Native macOS top system menu integration with standard application, file, edit, view, and window submenus.

🔌 Driver Resilience & Recovery UI (#666, #667, #668, #669)

• Extension driver crash recovery with automatic heartbeat monitoring, visual status banner, and 1-click manual restart button.
• Querya Extension Driver Mutation Standard specification and automated test suite (feat(extensions): Querya Extension Driver Mutation Standard (db.getTableSchema and db.mutate) #563, feat(extensions): Querya Extension Driver Mutation Standard (#563) #628).
• SDUI tree selection highlight for extension drivers (feat(tree): support active selection highlighting in SduiTreeBuilder for extension drivers #639, feat(tree): support active selection highlighting in SduiTreeBuilder for extension drivers (#639) #642).

🚀 Deep Memory & Performance Optimizations (#602, #603, #604, #605, #615, #616, #625, #627, #650, #651, #652, #653, #654, #655, #670, #671)

• String Interning Pool: Deduplicated low-cardinality string allocations in query result grids, slashing heap consumption.
• Compact Typed Storage & Lazy Cell Stringification: Primitive column vectors with deferred string conversions.
• Schwartzian Transform Grid Sorting: Precomputed sort keys in sortResultGridRows eliminating redundant comparison overhead.
• QuickSelect Median Calculation: O(N) median computation in GridSelectionCalcEngine.
• Background Compute Offload: Selection calculation engine offloaded to background workers.
• Filter Bar Debouncing & ResultsTab Memoization: Smooth 60 FPS typing without rebuild stutter.
• Resource Teardown: Hardened window closure and app lifecycle cleanup of timers and sockets.

🔒 Security, Storage & Dialect Fixes (#594, #595, #596, #597, #601, #607, #611, #617, #623, #629, #645, #648, #656, #657, #659, #660)

• In-memory secret scrubbing for database passwords.
• Redis safe disconnect and unhandled socket close protection.
• SQLite Write-Ahead Logging (WAL) and 5000ms busy timeout in LocalDb and workspaces.
• Monotonic SQL history ordering and batch pruning.
• DML distinction of literal 'NULL' string from SQL NULL, and leading zero preservation.
