Aaddrick 3506c14918 test(harness): add Linux compatibility test harness (#579) ...

Build out a Playwright-based regression-detection harness covering
the compat-matrix surfaces (KDE-W, KDE-X, GNOME, Sway, i3, Niri,
packaging formats). Adds:

- Planning + decision docs under docs/testing/ — README, matrix,
  runbook, automation, cases/ (11 case files), quick-entry-closeout
- Playwright scaffolding (config, tsconfig)
- 78 spec runners under tools/test-harness/src/runners/ — T## case-
  doc runners and S## distribution/smoke runners
- Substrate primitives in tools/test-harness/src/lib/: AX-tree
  loader (snapshotAx + waitForAxNode + axTreeToSnapshot), focus-
  shifter, eipc-registry, niri-native bridge, drag-drop bridge,
  electron-mocks, claudeai page-objects, inspector client

S03 (DEB Depends declared) and S04 (RPM Requires declared) ship
marked test.fail() — they're regression detectors for the case-doc
gap (deb.sh emits no Depends:, rpm.sh sets AutoReqProv: no), and
the expected-failure shape lets them report green on every host
until upstream packaging starts declaring runtime deps.

127 files, no runtime changes; harness is opt-in via
'cd tools/test-harness && npx playwright test'.
