Records the maintainers' decision on ADR-003: option C.

• .github/agents/squad.agent.md stays canonical and Copilot-only. Copilot's output is unchanged.
• Non-Copilot digests are self-sufficient and never point at Copilot's file (feat(coordinator): self-sufficient non-Copilot coordinators (ADR-003 option C, part 1 of #2487) #2489).
• Option B stays an opt-in spike (Spike: host-neutral canonical coordinator (ADR-003 option B), opt-in experiment #2488), not part of 2.0.

This closes the last #2487 done-when item that needed maintainer agreement. Docs only, with no code or projection change.

🟡 Changes recommended

An active documentation inconsistency remains: the host feature matrix does not reflect passing bridge/live scenarios and still shows the affected capabilities as unsupported because of known digest gaps.

What changed in this PR

This documentation-only PR records the maintainers’ acceptance of ADR-003 option C: Copilot retains its canonical coordinator file, while non-Copilot digests remain self-sufficient. Option B remains an opt-in experiment outside the 2.0 scope.

Changes:

• Updates ADR-003 status from Proposed to Accepted.
• Documents option C’s architectural decision and behavioral validation.
• Records option B’s follow-up scope and related implementation references.
