feat(hooks): add 7 hook templates with full install pipeline and extended trigger types

Extend HookTriggerType from 5 to 12 official events (Notification, SubagentStart,
SubagentStop, PreCompact, SessionEnd, PostToolUseFailure, PermissionRequest).
Add templates: stop-notify, auto-format-on-write, auto-lint-on-write,
block-sensitive-files, git-auto-stage, post-edit-index, session-end-summary
across notification/automation/indexing categories. Fix install pipeline to
use correct nested settings.json format with _templateId metadata for precise
detection. Redesign templates UI as responsive card grid with per-template icons.
