fix(#2844): verify-summary ignores future/prose path mentions; resolves project root (#2910)

* fix(#2844): verify-summary binds file-claim extraction to a creation-claim context

verify-summary's Pattern 1 matched any backticked path-like token with no
context check, so a prose mention of a future deliverable (`shared/types.ts`
in a 'next phase will add…' sentence) was checked for existence and its absence
failed the verdict on a healthy phase. #2685 added shape filtering but no
context check.

- src/verify.cts: both extraction patterns now require a claim label on the line
  (Created/Modified/Added/Updated/Edited/key-files). A bare prose mention no
  longer matches; genuine labeled claims still do.
- gsd-core/bin/gsd-tools.cjs: remove 'verify-summary' from SKIP_ROOT_RESOLUTION
  so relative claim paths resolve against the project root, not the raw cwd
  (subdirectory invocation no longer manufactures missing files).

Regression tests: prose mention not treated as a claim; prose-only SUMMARY
passes; absent claimed file still fails.

* chore(#2844): backfill changeset PR 2910
