fix(ui): compact crowded tabs and layer native browser overlays

[waleedlatif1]

Summary

• Size floating resource tabs from available space, shrinking to a compact control minimum before scrolling.
• Keep overlapping tooltips and menus above the native browser using the existing snapshot lifecycle, with bounded retries, hidden recapture, and cancelable preparation across resize and modal transitions.
• Add real Electron regression coverage for tab sizing and native browser overlays.

Type of Change

• Bug fix

Testing

• Real Electron regression test passed all nine scenarios; inspected tooltip and menu captures.
• Browser occlusion and native panel regression tests: 20 passed; regressions verified to fail before their fixes.
• All workspace type checks, full lint, all 49 audits, block registry audit, and docs manifest check passed.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

• In apps/desktop/e2e/fixtures/browser-chrome.tsx, the mount effect, ResizeObserver/heartbeat, and cleanup may call reportPanelBounds when api.browserAgent is unavailable, causing runtime errors; guard these calls as well.

<file name="apps/desktop/e2e/fixtures/browser-chrome.tsx">

<violation number="1" location="apps/desktop/e2e/fixtures/browser-chrome.tsx:69">
P3: `startBrowser` guards `api.browserAgent` before use, but the mount effect, its ResizeObserver/1 s heartbeat, and the cleanup all call `reportPanelBounds(api, ...)` / `api.browserAgent.setPanelBounds` without any availability check. In any context where `window.simDesktop` is absent (plain-browser load of the fixture page, or a shell without the browser-agent bridge), the effect throws a TypeError on mount and white-screens the fixture instead of the guarded 'Native browser bridge is unavailable' message. Guard once at the top of the effect.</violation>

[Medium risk] Adjusts browser panel overlay handling and tab layout logic.

The PR appears safe to merge; no new actionable issue or outstanding previous finding remains.

Summary

The PR makes crowded floating tabs shrink before scrolling and keeps menus and tooltips above the native browser using snapshots. It adds real-Electron regression coverage. Since the previous review, it removes mocked-call assertions in favor of that coverage.
