docs: close out Core 0.8.2 Intelligence Catalog

[eamirian]

Outcome

Reconciles Core documentation and evidence after the public ACE 0.8.2 Intelligence Catalog release.

Changes

• marks 0.8.2 as the current published developer preview;
• converts the catalog evidence packet from candidate to passed closeout;
• records the exact release commit, trusted publication run, PyPI hashes, and public-index-only three-package reproduction;
• keeps 0.9 Collaborative Intelligence and 1.0 stabilization explicitly unclaimed.

Verification

• roadmap, evidence-index, and package-identity tests: 29 passed;
• Ruff and formatting checks pass;
• documentation diff check passes.
