Honest test suite: 424/831 (51%) — all tests run, timeouts fail visibly

Browse Source 
Rewrote test architecture: deferred execution. Tests register thunks during
file load (try-call redefined to append to _test-registry), then the
Playwright loop runs each individually with 3s timeout via Promise.race.
Hanging tests (parser infinite loops) fail with TIMEOUT and trigger page
reboot. No tests are hidden or skipped.

Fixed generator: proper quote escaping for HS sources with embedded quotes,
sanitized comments to avoid SX parser special chars.

831 tests registered, 424 pass, 407 fail honestly:
- 22 perfect categories (empty, dialog, morph, default, reset, scroll, etc.)
- Major gaps: if 0/19, wait 0/7, take 0/12, repeat 2/30, set 4/25
- Timeout failures from parser hangs on unsupported syntax
