* test(bundler): cover properties-only spec registration

* refactor(testrun): extract prepareBundleInputs from Execute

* test(testrun): cover prepareBundleInputs aliases and missing-runtime error

* fix(cmd): point bundle-check aliases at pkg/spec/src

* test(cmd): smoke-test bundle-check resolves spec aliases

* test(cmd): table-test hier-check parse and FindAll on fixture

* test(cmd): unit-test buildBrowseURL deep-link vs root

* test(cmd): drop flaky TestRun_Doctor that launched real Chromium

* test(cmd): pin pipeline error to bundle resolution on web platform

* test(replay-ui): add bun test script

* ci(replay-ui): run bun test via make web-test target

* ci(replay-ui): point bun cache key at replay-ui/bun.lock

* refactor(replay-ui): share one statusFor between panels

* refactor(replay-ui): extract run-history derivation into lib module

* test(replay-ui): pin shared statusFor precedence and ordering

* test(replay-ui): pin run-history derivation alignment

* refactor(replay-ui): export clampIndex for testing

* refactor(replay-ui): extract keyboard-nav dispatch into pure module

* refactor(replay-ui): extract metrics formatters into lib module

* test(replay-ui): pin clampIndex step boundaries

* test(replay-ui): pin keyboard-nav ownership and key routing

* test(replay-ui): pin metrics formatters and path gap handling

* refactor(sidecar): expose device-output parsers as internal for testing

* test(sidecar): table-test device-output parsers against malformed input

* test(sidecar): cover logcat parsing year inference and line skipping

* test(sidecar): pin pressKey keycode mapping and unknown-key rejection

* test(sidecar): metrics bundleId falls back to launched app and honors override

* test(sidecar): loosen deadline upper bound to tolerate slow CI scheduling

* test(web-runtime): export selector builders for unit tests

* test(web-runtime): guard sanitize cycle, function, and depth limits

* test(web-runtime): table-test selector builder quoting and escaping
