fix(cli-registry): address PR B2 review — fix two test guards, drop unused catalogue

Two required fixes from Ark0N's review of #458:

1. test/frontend-cli-no-id-branching.test.ts's ALLOWED_BRANCHES keyed on
   <file>::<line>::<expression>. A single inserted line anywhere above an
   entry shifted every subsequent line number, so all 21 entries went stale
   simultaneously and the same 21 branches were reported as "new" — on a
   file six other open PRs also touch. Dropped the line number from the key
   (<file>::<expression>, matching the backend guard's own design), which
   collapses 21 line-keyed entries to 11 or-collapse where the same
   expression recurs at multiple call sites in the same file.

2. test/run-mode-ui.test.ts's terminal-ownership guard scanned method
   bodies via `^ {2}async (run[A-Za-z]*)\(\) \{$`, which matched the 8
   one-line run<Mode>() wrappers PR B2 introduced but not _runCliMode(mode),
   where the real logic (and the actual risk the guard exists to catch) now
   lives. Fixed the regex to `^ {2}async (_?run[A-Za-z]*)\(\w*\) \{$` and
   added _runCliMode to the sanity list. Same-class fix in
   test/opencode-resize.test.ts, which had the identical blind spot via
   runOpenCode.toString().

Both reproduced live before fixing (inserted the same comment line; added
this.terminal.clear() to _runCliMode) to confirm the bug, then confirmed
the fix catches it and the suite stays green otherwise.

Also resolves Open Question 2 by dropping window.__codemanCliCatalog
entirely: nothing consumed it, and a registry DECLARED_FOR_LATER field
costs nothing until read while an unconsumed script tag on every page
render is a different trade. Reverts Phase 1 cleanly — server.ts's
injection, shortBadge back in types.ts's DECLARED_FOR_LATER list and the
pinned guard test, and the three associated render-index-html.test.ts /
server-index-title.test.ts assertions.

Full gate: 405 files / 7717 tests / 0 failures (net unchanged), typecheck/
lint/format clean.
