fix: wire after_tasks and after_implement hook events into command templates (#1701)

The HookExecutor backend in extensions.py was fully implemented but
check_hooks_for_event() was never called by anything — the core command
templates had no instructions to check .specify/extensions.yml.

Add a final step to templates/commands/tasks.md (step 6, after_tasks) and
templates/commands/implement.md (step 10, after_implement) that instructs
the AI agent to:

- Read .specify/extensions.yml if it exists
- Filter hooks.{event} to enabled: true entries
- Evaluate any condition fields and skip non-matching hooks
- Output the RFC-specified hook message format, including
  EXECUTE_COMMAND: markers for mandatory (optional: false) hooks

Bumps version to 0.1.7.

+- **Extension hooks never triggered (#1701)**: Wired `after_tasks` and `after_implement` hook events into their respective command templates
+  - `templates/commands/tasks.md` now includes a final step that reads `.specify/extensions.yml`, evaluates registered `after_tasks` hooks (respecting `enabled` flag and `condition`), and outputs the correct hook message format — including `EXECUTE_COMMAND:` markers for mandatory hooks
+  - `templates/commands/implement.md` does the same for `after_implement` hooks
+  - The `HookExecutor` backend in `extensions.py` was already complete; only the template wiring was missing
