* Match `gsd-sdk query commit` in graphify auto-update hook (#3653)
The PostToolUse Bash hook only substring-matched direct shell git ops in
tool_input.command. `gsd-sdk query commit` invokes git via spawnSync,
so the literal "git commit" never appears in the Bash tool's command
string and the hook silently skipped every SDK-issued commit. Result:
.planning/graphs/ drifted stale after every phase that closed via
gsd-sdk query commit, with no error and no log.
Gate 2 now also matches `gsd-sdk query commit`. Other SDK verbs
(phase.complete, roadmap.update-plan-progress, state.begin-phase) do
not invoke git themselves and remain non-matching to avoid spurious
rebuilds per state mutation. Adds positive + negative matcher tests.
