test: cover preset constitution seeding through init CLI (#3297)

* Fix preset-constitution-not-installed: use PresetResolver in constitution setup

Apply the remediation from the bug assessment on issue #3272.

Changes:
1. Modify ensure_constitution_from_template (init.py) to resolve the
   constitution-template through the preset priority stack via
   PresetResolver, instead of hardcoding the core template path. This
   ensures a preset's replacement constitution-template is used when
   seeding .specify/memory/constitution.md.

2. Reorder init flow: move ensure_constitution_from_template to after
   the preset installation block so that 'specify init --preset' seeds
   the memory file from the already-resolved template stack, not from
   the generic template that existed before the preset arrived.

3. Add _maybe_reseed_constitution to PresetManager (presets/__init__.py):
   a post-install hook that re-seeds .specify/memory/constitution.md
   from the preset's constitution-template during 'specify preset add'
   on an existing project, but only when the memory file still contains
   generic placeholder tokens ([PROJECT_NAME] or [PRINCIPLE_1_NAME]).
   Legitimately authored constitutions (no placeholder tokens) are never
   overwritten.

4. Add regression tests covering both code paths (TestConstitutionReseedOnPresetInstall
   and TestEnsureConstitutionFromTemplate in tests/test_presets.py).

* Harden preset constitution resolution

Use manifest-aware composed content, atomic safe writes, and conservative generic-template matching for constitution seeding and re-seeding.

* Limit preset CLI change to regression test

Remove accidental whole-file Ruff formatting introduced during conflict resolution so the PR contains only the intended end-to-end test.

* Make preset init test depend on init ordering

Disable preset-install lifecycle seeding in the regression test so it fails unless init materializes the constitution after registering the preset.
