feat(#985): intel command cutover — commands-only capability, last first-party family (ADR-857 phase 4d-impl-4) (#988)

* feat(#985): intel command cutover — commands-only capability, last first-party family (ADR-857 phase 4d-impl-4)

Migrate the intel CLI command family from a hardcoded gsd-tools.cjs case arm to
a registry-dispatched Capability (commandFamilies mechanism, #961), mirroring
the graphify (#972) and audit (#984) cutovers. New src/intel-command-router.cts
exports routeIntelCommand reproducing all 9 subcommands verbatim (incl. the
status timeAgo non-raw post-processing), lazily requiring intel.cjs inside the
route fn. capabilities/intel/capability.json declares the intel command family;
commands-only (skills:[]), declares the existing intel.enabled gate (default
false — behavior unchanged).

Behavior-CHANGING (dispatch path) but equivalence-proven: CLI output identical;
existing intel.test.cjs passes unchanged. Completes the first-party command-
family cutover sequence (graphify/audit/intel).

Closes #985

* test(#985): compute expected planningDir via path.join in intel cutover unit tests (Windows CI)

The intel-command-cutover unit-mock assertions hardcoded a POSIX `/.planning`
expectation while the router builds it with path.join(cwd, '.planning') →
backslashes on Windows, so the planningDir-arg assertions (query/status/diff/
snapshot/validate/update/api-surface) failed only on windows-latest CI. Compute
the expectation with path.join (cross-platform); production router unchanged.
