fix(hooks): close Qwen Code hooks gaps (events, http, sequential/disableAllHooks) - #1951

Summary

Closes the three Qwen Code hooks gaps reported in #1925.

Issue: #1925
Ref: #1888

Changes

1. Missing events TodoCreated, TodoCompleted, StopFailure

• Added canonical events todoCreated, todoCompleted, and stopFailure to the
  HookEvent union in src/types/hooks.ts.
• Mapped them in QWENCODE_HOOK_EVENTS and CANONICAL_TO_QWENCODE_EVENT_NAMES
  (⇄ TodoCreated / TodoCompleted / StopFailure).
• Safety: every other tool adapter filters config.hooks against its own
  *_HOOK_EVENTS set (supported.has(event)), and unknown event names fall
  back via ?? eventName. The new canonical events are therefore only emitted
  by Qwen Code; no other tool adapter changes behavior. Confirmed by reading the
  shared tool-hooks-converter.ts and the claudecode / copilotcli /
  copilot adapters, and by the full test suite passing.

2. http hook type was lossy on import

• qwencodeHooksToCanonical previously coerced any non-command/prompt hook
  (including http) to command, dropping the transport. It now preserves
  http and its target url.
• Added a url field to the canonical HookDefinitionSchema so the URL
  round-trips, and updated copilotcli-hooks.ts to keep passing url through
  for its http export now that url is a canonical (no longer passthrough) key.

3. Group-level sequential and top-level disableAllHooks not round-tripped

• QwencodeMatcherEntrySchema now reads sequential (per matcher group), stored
  per canonical definition and re-emitted when any definition in a group opts in
  (Qwen defaults to parallel, so it is only written when true).
• disableAllHooks is captured into the qwencode namespace on import and
  written back to .qwen/settings.json on export.

Tests

• Extended qwencode-hooks.test.ts: generate + import round-trip for the three
  new events, http type/url preservation on import and export, and
  sequential / disableAllHooks round-trip.
• Preserved the Tool × Feature happy-path e2e tests (e2e-hooks.spec.ts, 52
  passing).
• Synchronized docs/reference/file-formats.md and the generated
  skills/rulesync/file-formats.md.
