* feat(app): add persistent workspace side panes
Keep the common review and file-browsing workflow beside the active agent without tearing down pane contents. Workspace tabs now share one compact chip language, assistant file links route into the retained right pane, and diff/file trees share stable geometry.
* fix(app): localize pull request empty state
* test(app): update explorer pane coverage
* fix(app): preserve explorer pane workflows
* test(app): make explorer tab selection idempotent
* fix(app): persist workspace review pins
* fix(app): preserve sidebar scrim drag hook
* fix(app): restore companion pane interactions
* test(app): follow selected sidebar surface
* perf(app): virtualize large diff rendering
Render bounded diff row groups through one vertical list and one horizontal surface. Bound retained list ranges when expansion grows the data set so large diffs paint promptly without sacrificing scrolling behavior.
* refactor(app): normalize working tree diff options
* fix(app): keep wide diff text reachable
* fix(ci): skip unrelated required checks cleanly
Matrix jobs had to start no-op runners to preserve interpolated required-check names. Static named jobs let GitHub report genuine skipped conclusions while keeping those names stable.
* fix(ci): gate changes to install patching script
* fix(ci): route cross-package test contracts narrowly
* fix(ci): keep routed contracts merge-blocking
* fix(server): exclude nested test utilities from builds
* fix(ci): cover app-owned native and browser domains
* refactor(ci): align tests with runtime domains
Own browser specs, desktop specs, and Electron-only app code by stable directories so PR routing does not depend on filename conventions. Keep desktop integration coverage inside the required desktop check.
* fix(ci): keep routing and desktop suites isolated
The routing regression must run before dependency installation, and desktop Vitest must not collect Playwright-owned specs.
* fix(ci): isolate desktop e2e runtime
* perf(test): isolate Playwright workers
* perf(test): parallelize Playwright within specs
* fix(test): keep Playwright file scheduling
* fix(test): share dynamic Metro fixture
* fix(test): preserve own-host restart fixtures
* fix(ci): preserve routed contracts after rebase
* Stabilize Playwright wheel-scroll assertions
