Mohamed Boudra 0f7fa55a0f Centralize platform gating and fix iPad/tablet support
Add `packages/app/src/constants/platform.ts` with canonical gates
(isWeb, isNative, getIsElectron) and refactor all ~100 ad-hoc
Platform.OS checks across 69 files to use shared imports.

Fix sidebar hover crash on native (onPointerEnter → onHoverIn),
fix tooltip to use breakpoint instead of platform detection, make
sidebar action buttons always visible on native where hover doesn't
work, and document the platform gating decision matrix in CLAUDE.md.

/**
* VS Code-style titlebar drag region for Electron.
*
* Copied from VS Code at commit daa0a70:
* - titlebarPart.ts:463-464 → prepend(container, $('div.titlebar-drag-region'))
* - titlebarpart.css:57-64 → position: absolute, full size, -webkit-app-region: drag
* - titlebarpart.css:249-260 → top-edge resizer, no-drag, 4px
*
* VS Code's drag region is a static DOM element — no z-index, no pointer-events,
* no state, no event listeners. Interactive elements get no-drag from their own
* CSS (global backstop in index.html). The drag region never re-renders.
*
* The resizer is Windows/Linux only (titlebarpart.css:249 scopes to .windows/.linux).
* On macOS, Electron handles edge resize natively.
*/
/**
* Static drag overlay and top-edge resizer. Returns null on non-Electron.
