feat(v3.12.0): media pipeline, AI image generation, capability probe, companion v2.9.0

Three-month batch sync from internal repo (~80 commits) covering Tracks F.5a, F.7e, F.8, F.17, F.18, F.X. WordPress media pipeline - Pillow-based optimization, AI image generation (OpenAI / Stability / Replicate / Google Nano Banana / OpenRouter), chunked + resumable uploads, bulk delete/reassign, idempotent retries. Capability discovery (F.7e) - Per-site credential probe + adapters for WordPress / WooCommerce / Gitea, tier-fit unions granted ∪ roles, capability badge UI with HTMX partial re-check, install hint in every companion-unreachable error. Companion plugin overhaul - Renamed wordpress-plugin/airano-mcp-seo-bridge → wordpress-plugin/airano-mcp-bridge. - Eight new endpoints: /capabilities, /bulk-meta, /export, /cache-purge, /transient-flush, /site-health, /audit-hook, /upload-and-attach. - wp.org Plugin Check pass: i18n, WP_Filesystem, scheme allowlist on audit-hook URL. Other - Gitea ergonomics (F.17): batch files, tree, search, compare, releases, fork. - Opportunistic bcrypt upgrade for legacy SHA-256 admin keys (F.8). - n8n refactor: structured errors, capability probe, missing tools backfilled. - Idempotency-Key dedup for AI media upload retries; WP client fast-fails on unreachable sites. Docs - README + CLAUDE.md drop the fixed "633 tools" claim. The total grows with each release; per-plugin approximations + dashboard-surfaced counts replace it. - Tools/Tests badges removed in favour of "Plugins: 10". Deployment - PyPI mirror chain, optional BUILD_HTTP_PROXY, Alpine→Yandex apk mirror, Debian-slim Plan-B Dockerfile, mirror.gcr.io variant. CI - Black + Ruff clean on Python 3.12; pytest tests/ green.
