* test(#4667): add failing-first coverage for the codex @-include rewrite
Behavioral end-to-end: a real in-process install(true,'codex') into a temp
CODEX_HOME must leave zero @~/.claude includes in GSD-owned .md artifacts,
rewrite the issue's own example include to @~/.codex/, keep the deliberate
_GSD_RUNTIME_ROOT .claude fallback chains byte-identical, and stay
idempotent across a reinstall (no doubled prefix). All four are RED until
the installer grows the manifest-scoped rewrite pass.
* fix(#4667): rewrite codex @ includes to the codex install root
Codex-installed agents and commands kept @~/.claude/gsd-core/... (and
@/Users/trekkie/.claude/gsd-core/...) include references pointing into the Claude
install: silent wrong-copy reads on dual-runtime machines at divergent
versions, missing files on codex-only ones. Several emitters bypass the
per-runtime converters, so the per-emitter fixes since #570 rotted.
Adds a manifest-scoped rewrite pass in install() beside the leak scanner:
for codex, every manifest-tracked .md/.toml artifact has the @-include
forms rewritten to the codex root. The pass matches the exact include
literal only — the _GSD_RUNTIME_ROOT/$PREFERRED_CONFIG_DIR fallback
chains, prose .claude mentions, and CHANGELOG.md are untouched — and runs
before the scanner, which remains the verification backstop for anything
a future emitter introduces.
* test(#4667): cover the HOME-anchored include form and sync the pass comment
Adds behavioral coverage for the second rewrite literal
(@$HOME/.claude/gsd-core/ -> @$HOME/.codex/gsd-core/) via the
plan-review-convergence command, and corrects the pass's comment: the
agent .tomls are generated after it and prefix themselves, so the .toml
branch of the rewrite is inert by design.
* test(#4667): baseline the offline upgrade against the deployed tree (sanctioned)
* chore(#4667): backfill changeset PR number (4858)
* test(#4667): sandbox the install home in the include-rewrite tests (#3712 guard)
* test(#4667): install via subprocess with an isolated env in the include-rewrite tests
