fix: replace stale /review-council refs with /uf.review-council in AGENTS.md

[yvonnedevlinrh]

After the uf. namespace migration (unbound-force/unbound-force#304), AGENTS.md still references old unprefixed command names. Agents following AGENTS.md will invoke commands that no longer exist in .opencode/commands/.

Change

Replace /review-council with /uf.review-council in AGENTS.md (approx. lines 89, 93, 99 — verify current positions).

Why

uf init classifies AGENTS.md as user-owned (isToolOwned() returns false), so command references inside it are not auto-migrated.

Acceptance Criteria

• AGENTS.md uses /uf.review-council (and any other renamed commands)
• Substring-safe grep for old unprefixed command names returns zero matches (must not match /uf.review-council)

Triage: VALID — bug

The Divisor review panel (5 reviewers: Adversary, Architect, Guard, SRE, Tester) unanimously classifies this as a valid, objective bug.

Confirmed: AGENTS.md references /review-council at lines 89, 93, 99, but the command file on disk is .opencode/commands/uf.review-council.md — the unprefixed command no longer exists. Agents following AGENTS.md will invoke a non-existent command, silently bypassing the mandatory Review Council Gate (a MUST-level requirement in the constitution).

Scope note (flagged by 4/5 reviewers): The same stale /review-council references also appear outside AGENTS.md. Consider expanding the acceptance criteria to a project-wide grep, or filing companion items:

• .specify/memory/constitution.md (lines 10, 133) — highest-authority governance doc; may warrant a PATCH version bump per its own amendment protocol
• .opencode/skills/review-context/SKILL.md (line 19) — actively consumed by agents
• docs/reference/cli/init.md, .opencode/agents/cobalt-crush-dev.md — user-facing / agent-facing docs
• AGENTS.md line 531 is a historical changelog entry (spec 017); reviewers suggest exempting changelog/history mentions from the grep criterion to preserve historical accuracy.

Verification tip (Tester): Acceptance criterion #2 needs a substring-safe pattern to avoid matching the new name, e.g. rg -P '(?<!uf\.)/review-council'.

Documentation-only change — exempt from the spec workflow and council review. Root cause (auto-migration of user-owned refs) is tracked in unbound-force/unbound-force#419.
