fix(hooks): merge marketplace plugin hooksConfigs into claude-code-hooks at config time

Previously, loadPluginHooksConfigs() loaded plugin hooks from marketplace
plugins (hookify, superpowers, zzcommon, zzfe, etc.) into
pluginComponents.hooksConfigs, but config-handler.ts never consumed them.
This meant plugin hooks were discovered but never merged into the runtime
hooks dispatch system.

Changes:
- Extend ClaudeHookEvent and ClaudeHooksConfig to support all 12 event
  types (PostToolUseFailure, PermissionRequest, Notification,
  SubagentStart, SubagentStop, SessionStart, SessionEnd) in addition to
  the existing 5
- Add ALL_HOOK_EVENT_TYPES constant as single source of truth for event
  type iteration
- Add mergePluginHooksConfigs() to unwrap plugin HooksConfig (with hooks
  wrapper) into flat ClaudeHooksConfig, filtering out unsupported
  prompt/agent hook types
- Add setPluginHooksConfigs() to store pending plugin configs and
  invalidate the config cache
- Create applyHookConfig() handler following existing applyXxxConfig
  pattern, wired into config-handler after loadPluginComponents()
- Extend DisabledHooksConfig and mergeDisabledHooks for all 12 events

Closes #4179
