scripts/fix-slash-commands.cjs SEARCH_DIRS did not cover agents/, sdk/src/,
or top-level files, so 9 colon-form references survived in 6 files. The hit
at agents/gsd-codebase-mapper.md:105 propagated into ~/.claude/agents/ at
install time (the fixer is not wired into install) and produced unrunnable
/gsd:<cmd> suggestions in agent output on non-Gemini runtimes.
This commit includes Pass 1 (the 9 line edits) AND Pass 2 (extending the
fixer's SEARCH_DIRS so future regressions are auto-rewritten and caught by
the bug-2543 guard, which mirrors that list). The standalone bug-3100 test
added in the prior revision is removed in favor of the bug-2543 guard's
extended scan, per CONTRIBUTING.md test standards (no source-grep tests on
non-.md files).
