* feat: add bundled lean preset with minimal workflow commands
Add a lean preset that overrides the 5 core workflow commands (specify,
plan, tasks, implement, constitution) with minimal prompts that produce
exactly one artifact each — no extension hooks, no scripts, no git
branching, no templates.
Bundled preset infrastructure:
- Add _locate_bundled_preset() mirroring _locate_bundled_extension()
- Update 'specify init --preset' to try bundled -> catalog fallback
- Update 'specify preset add' to try bundled -> catalog fallback
- Add bundled guard in download_pack() for presets without download URLs
- Add lean to presets/catalog.json with 'bundled: true' marker
- Add lean to pyproject.toml force-include for wheel packaging
- Align error messages with bundled extension error pattern
Tests: 15 new tests (TestLeanPreset + TestBundledPresetLocator)
* refactor: address review — clean up unused imports, strengthen test assertions
- Remove unused MagicMock import and cache_dir setup in download test
- Assert 'bundled' and 'reinstall' in CLI error output (not just exit code)
- Mock catalog in missing-locally test for deterministic bundled error path
- Fix test versions to satisfy updated speckit_version >=0.6.0 requirement
* refactor: address review — fix constitution paths, add REINSTALL_COMMAND to presets.py
- Fix constitution path to .specify/memory/constitution.md in plan, tasks,
implement commands (matching core command convention)
- Include REINSTALL_COMMAND in download_pack() bundled guard for consistent
recovery instructions across bundled extensions and presets
* refactor: address review — explicit feature_directory paths, ZIP cleanup in finally
- Prefix spec.md/plan.md/tasks.md with <feature_directory>/ in plan, tasks,
and implement commands so the agent doesn't operate on repo root by mistake
- Move ZIP unlink into finally block in init --preset path so cleanup runs
even when install_from_zip raises (matching preset_add pattern)
* refactor: address review — replace Unicode em dashes with ASCII, fix grammar
- Replace all Unicode em dashes with ASCII hyphens in preset.yml and
catalog.json to avoid decode errors on non-UTF-8 environments
- Fix grammar: 'store it in tasks.md' -> 'store them in tasks.md'
* refactor: address review - align task format between tasks and implement
- Remove undefined [P] marker from implement (lean uses sequential execution)
- Clarify checkbox update: 'change - [ ] to - [x]' instead of ambiguous '[X]'
- Simplify implement to execute tasks in order without parallel complexity
* refactor: address review - parse frontmatter instead of raw substring search
- Use CommandRegistrar.parse_frontmatter() to check for scripts/agent_scripts
keys in YAML frontmatter instead of brittle 'scripts:' substring search
