fix(#503): detect local Antigravity (.agent) installs in /gsd:update (#512)

* fix(#503): detect local Antigravity (.agent) installs in /gsd:update

The installer places local Antigravity installs in ./.agent/
(bin/install.js getDirName('antigravity') === '.agent'), but the
/gsd:update detection cascade in update.md only knew the global
Antigravity layout (.gemini/antigravity{,-ide,-cli}). A local .agent
install fell through to the `Otherwise -> claude` default, so the
update refreshed Claude artifacts instead of the Antigravity install.

Add `.agent` -> antigravity to all four runtime-dir surfaces in
update.md: the execution_context path classifier, the RUNTIME_DIRS
candidate array, the local-scope discovery loop, and the post-update
cache-clear loop (the last otherwise left a stale update indicator on
local Antigravity installs).

Note: the issue also cited update-context.cjs, which does not exist on
`next` (it is introduced by the still-open PR #499). The same .agent
fix should be carried into update-context.cjs when #499 lands.

**`/gsd:update` now detects local Antigravity (`.agent`) installs** — local Antigravity installs live in `./.agent/`, but the update detection cascade in `update.md` only knew the global `.gemini/antigravity{,-ide,-cli}` layout, so a local install was misclassified as `claude` and refreshed Claude artifacts instead. `.agent` → antigravity is now mapped across all four runtime-dir surfaces (path classifier, `RUNTIME_DIRS`, local-scope discovery loop, and the post-update cache-clear loop).
