程序员阿江(Relakkes) 1aefc402ce build(policy): fix four lexer desyncs and extend the dead-import check to all of src
The check landed scoped to src/server/ws because blanking desynced on 6 of
2149 files and a desync reports a live import as dead. All four causes are
fixed, so the scope is now every source root no compiler checks — src,
scripts and adapters — and 0 of 2541 files desync.

The bugs, each with a regression test that places the import's only
reference after the construct so a desync makes it go dead:

- The token before a slash was read back out of the raw source, so the last
  word of a preceding comment decided whether `/` opened a regex. In
  useIssueFlagBanner.ts `// …correction tone` made the next line's regex lex
  as a division, and its apostrophe opened a string that ate the line. A
  comment is whitespace to the grammar; it now contributes nothing.
- That token accumulated across whitespace, so `return false` became one
  token named `returnfalse` and the following `return /re/` no longer looked
  like a keyword. This is what broke markdownImages.ts and dead-imports.ts
  itself.
- `input! / 10` divides but `!/re/.test(x)` negates, and both put `!` before
  the slash. What precedes the `!` settles it.
- Character classes and quotes inside regular expressions, fixed earlier.

desktop/ stays out of scope: its tsconfig already sets noUnusedLocals, and
scanning it anyway finds nothing — the cross-check that this agrees with a
real compiler. `blankingIsSound` still refuses to analyse a file whose
blanked form no longer parses, so a future desync is reported, not acted on.

Routing follows the scope: policyPrefixes now names adapters/, scripts/ and
src/ instead of the three scripts/ subdirectories and src/server/ws/. The
check reads these files rather than importing them, so the import graph
cannot select the lane on its own. `does not widen docs, policy, or coverage
lanes` split in two — its fixture selects the policy lane through its own
files now, so the dependent-must-not-widen invariant moved to a desktop
fixture that still shows it.

Verified by mutation, each reverted from an explicit backup: planting
`plantedProbeSymbol` into one file per root reported all four and failed
check:policy; reverting each of the three lexer fixes failed exactly its own
regression test; removing 'src/' from policyPrefixes failed the routing test
and made change-policy report policy=false for a src-only diff.

check:policy is 223 pass / 0 fail in 8.6s, up from 2s — the scan is 3.8s
over 2150 files and the planted-import test covers every one of them.
