docs: refresh agent roster and fix stale counts (203 agents / 14 divisions)

The README Stats and acknowledgements were stale (144 / 147 agents, "12
divisions") and 19 merged agents were missing from the division tables.

- Update both count statements to 203 agents across 14 divisions
- Add 19 missing roster rows: Design (1), Engineering (4), Marketing (5),
  Project Management (1), Sales (1), Specialized (7)
- De-hardcode the Gemini CLI README ("61 Agency agents" -> "all Agency
  agents") so it can't go stale again

Verified: every on-disk agent is now linked in the README (0 missing).

Thanks to the contributors whose agents are now cataloged — @epowelljr,
@hedonnn, @Subhodip-Chatterjee, @Shiven0504, @DKFuH, @ahteshamsalamatansari,
@ahruslan17, @lz-googlefycy, @jmlozano1990, @kriptoburak — and everyone
building out The Agency.
