TrustBeacon 0.1.12 - validation and packaging

133 local checks/assertions passed on PHP 8.3.6:
- DKIM fixtures: 39
- Service/abilities fixtures: 30
- Runner: 4
- Presentation: 22
- Rendering and notice HTML: 38
PHP syntax and JSON Schema Draft 4 checks passed.

Local tests use deterministic DNS and WordPress stubs. Development tests are preserved in the separate development archive and excluded from the installable ZIP. The declared languages directory is included. INFO rows display Not scored.

Live evidence from installed 0.1.11 on itechguide.com, WordPress 7.1.3:
- Both TrustBeacon abilities discovered and their schemas read through WPVibe.
- run-audit executed independently using selector vps2026.
- get-last-audit returned the same completed_at timestamp, 2026-10-18T00:07:13+00:00, and the same score, 74.
- DKIM public key passed supported DNS/key checks. Message authentication remains not_tested.
- The user supplied dashboard audit screenshots and Plugin Check reports.

0.1.12 has the same audit and ability code as 0.1.11. Only version metadata, packaging, documentation, translation-folder presence and INFO score rendering changed.

Remaining acceptance:
- Install 0.1.12 and rerun Plugin Check on the final production package; this has not been claimed clean.
- Check the INFO label and dashboard appearance visually.
- Verify HTTP ability execution is denied for a nonadministrator (unit checks passed; live lower-permission credentials were not available).

Do not publish until acceptance is complete. No installation or public publication was performed by this build process.
