v2.6.0 — The Agent Card Edition

A real agent.fafa passport, MCP Server Card, and AI Catalog entry — gemini-faf-mcp joins the wider agent-discovery ecosystem.

• agent.fafa — a real FAF Agent Card, authored from live introspection of server.py's actual 12 tools (name + docstring, not guessed or copied from another server's tool list).
• MCP Server Card (SEP-2127) — faf cards --target mcp, carries the FAF context block by construction.
• AI Catalog entry — .well-known/ai-catalog.json, faf cards --target catalog. Fresh spec (ratified Nov 2025) — early adoption.
• GEMINI.md — regenerated with a genuinely richer template (Setup & build, Test & verify, Where things live, a universal "Before changing things" safety default) instead of the old thin project/goal/language-only output.
• fastmcp floor — >=3.4.0 → >=3.4.7 (7 patch releases since June).
• project.faf data hygiene — was 5 months stale. Added project.version and project.title (both previously missing, causing generated cards to silently fall back to 0.1.0/no title); corrected a separately-stale state.version (2.2.0, real: 2.6.0); refreshed the generated timestamp.
• .gitignore — no longer hides .faf-dna (a real birth-certificate lineage file, dated 2026-03-12, invisible to git until now) or .well-known/ — both now tracked.
• Removed a stale, never-tracked, factually-wrong hand-rolled .well-known/mcp/server-card.json (wrong version, a fabricated tool name) — superseded by the real generated card above.

Not in this release: A2A support. faf cards --target a2a correctly refuses to fabricate an endpoint gemini-faf-mcp doesn't serve — real A2A support is planned as its own future release, not bundled into this one's story.

Trophy 100%, 17/17 slots, throughout.
