Release 0.12.1

[jothimani-rajendran]

What

This is a patch release that ships #175: plugin hooks now start their runtime through the shipped scripts/launch.sh instead of a bare python3, so they run on Windows. It follows the same pattern as #174 (0.12.0) and touches only version surfaces:

• pyproject.toml, CITATION.cff and the action.yml default are now 0.12.1.
• The pinned action refs in docs/installation.md and docs/reviewer-evidence.md now point at 0.12.1.
• docs/assets/social-preview.svg and .png were regenerated with gen_brand_assets.py, which rendered "15 agents, 9 surfaces, 8 commands, v0.12.1".
• The CHANGELOG "Unreleased" entry is now "0.12.1 — Plugin hooks that start on Windows".

Why a patch release: the change is in the plugin builders, not the policy emitters. test_emitter_stability still compiles its golden fixtures byte-identically, so the PATCH contract holds.

After merge, the owner cuts the v0.12.1 tag. chock-catalog then re-adopts at that tag.
