Enforce maintained regression checks

[parsakhaz]

Summary

• add PR CI coverage for root typecheck/lint, minimal Playwright smoke, and cross-OS main-process tests
• replace stale browser smoke assumptions with a deterministic renderer preload mock
• remove obsolete Playwright specs that no longer matched the current UI/test contract

Validation

• ruby YAML parse for .github/workflows/quality.yml
• pnpm typecheck
• pnpm lint (passes with existing warnings)
• CI=1 pnpm --filter main test
• PANE_DIR=/tmp/pane-pr-ci-* xvfb-run -a pnpm test:ci
• PANE_DIR=/tmp/pane-min-ci-* xvfb-run -a pnpm test:ci:minimal

Notes

• Local shell reports Node 20.19.3, while repo requires >=22.14.0. CI uses Node 22.15.1.
• The current Playwright suite is intentionally reduced to maintained smoke coverage. Broader real Electron IPC E2E should be rebuilt as a follow-up using a proper Electron harness.
