What & why

Component tests for the Lit dashboard: 31 spec files, 892 tests, covering all 31
elements (was 13). Plus the ~30 bugs writing them found, and pnpm typecheck —
a type gate that actually runs — wired into CI alongside the new suite.

To retire manual UI regression. The tests did that, but the more useful outcome
was what they exposed: six existing specs asserted broken behaviour as expected
and eight could not fail at all, so the gaps looked closed. And tsc had been
exiting on a deprecated option before checking anything, with nothing in CI
running it, which is how 28 type errors and a file that hadn't compiled since
June went unnoticed. Every assertion added here is mutation-checked: break what
it guards, confirm it fails.

Greptile Summary

Adds broad component and unit-test coverage for the Lit dashboard, fixes behaviors exposed by those tests, and introduces CI-enforced type checking and browser component tests.

• Expands dashboard coverage across shell, sidebar, workbench, panel, player, and tab components.
• Corrects UI state derivation, rendering, filtering, trace display, and controller behavior.
• Updates shared, core, backend, adapter, and injected-script contracts and utilities.
• Adds a working TypeScript gate and separate browser component-test CI job.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
