test(#4516): migrate per-runtime install/upgrade adapters to named timeout constants (#4582)

Batch 5 of the ad hoc timeout literal migration (epic #4445). Replaces
every bare numeric timeout/timeoutMs object-literal property across
tests/augment-upgrades.test.cjs, tests/shared-hooks-dir-resolution.test.cjs,
tests/antigravity-upgrades.test.cjs, tests/cursor-hooks.test.cjs,
tests/cursor-hook-workspace-roots.test.cjs, tests/gemini-runtime-removed.test.cjs,
tests/kilo-upgrades.test.cjs, tests/kimi-upgrades.test.cjs,
tests/kimi-variant-disambiguation.test.cjs, tests/opencode-plugin-adapter.test.cjs,
tests/windsurf-hooks-bridge.test.cjs, tests/effort-sync-installed-runtime.test.cjs,
and tests/hooks-commonjs-marker.test.cjs with a named constant, per
eslint-rules/no-adhoc-timeout-literal.cjs. Removes these 13 files from the
rule's allowlist.

Adds one new shared constant to tests/helpers/timeouts.cjs for spawning a
single already-staged hook script directly (a heavier class than the
existing quick-spawn norm), shared across three files in this batch. One
new file-local constant covers a property-test driver process distinct
from any existing class. Every other site reuses an existing shared norm.
No src/bin file touched, no numeric timeout value changed anywhere.
