fix: add self-check checklist to plan expert for format enforcement (#783)

* fix: add self-check checklist to plan expert for format enforcement

Plan was generating old-format sections (3 Test Queries, Success Criteria,
Failure Conditions) instead of the new format. Add explicit binary self-check
rules that must pass before plan.md is finalized:
- Exact section name matching (reject old names)
- Single test query enforcement
- Every signal must be a concrete command, not observation
- No soft language in signals
- Domain constraint coverage mapping

* fix: simplify section name check to reject any extra sections

* fix: enforce user-specified team name as coordinator expert name

The model was appending "-coordinator" to the user's team name (e.g.,
"bash-gaming" became "bash-gaming-coordinator"). Add explicit instruction
that the coordinator name must be the exact team name with no suffix.

* fix: refine expert naming rules — conditional team name, verb-based delegates

- Coordinator: use user-specified team name if given, no suffixes
- Delegates: name by function (@name/test, /verify, /build), not persona
  (/tester, /coder, /designer)

+Delegation tree with role assignments.
+
+Naming rules:
+- Coordinator: if the user specified a team name, use it exactly — no "-coordinator", "-main", or other suffixes.
+- Delegates: `@coordinator-name/verb-or-function` — name by what they do, not who they are. Use `/test`, `/verify`, `/plan`, `/build`, `/write`, not `/tester`, `/coder`, `/designer`. The name should be self-explanatory at a glance.
+
+Include one verifier expert that executes the hard signal checks defined in Verification Signals — the generator and the verifier share no context (context separation). The verifier is a single expert with exec capability, direct child of the coordinator, not nested under an executor.
 
 For each expert, write ONLY: name, one-line purpose, and role (executor or verifier). Do not write deliverables, constraints, or implementation details — that is write-definition's job.
 
+## Self-Check Before Finalizing
+
+Re-read plan.md and verify each rule. If any check fails, fix plan.md before attemptCompletion.

+1. **Section names exact match**: plan.md uses exactly these section names and no others — "Expert Purpose", "Domain Knowledge", "Use Cases", "Test Query", "Verification Signals", "Architecture". Extra sections confuse downstream experts.
+2. **Single test query**: "Test Query" section contains exactly one query, not multiple.
+3. **Every signal is a command**: each entry in "Verification Signals" specifies a concrete command to execute and its expected result. Entries that describe what to observe or what correct output "looks like" without a command are not signals — rewrite them.
+4. **No soft language in signals**: signals contain no phrases like "verify that", "check that", "should be", "looks correct", "works properly". Each signal is: run X → expect Y.
+5. **Domain constraint coverage**: every constraint in "Domain Knowledge" is exercised by at least one signal. List which signal covers which constraint.
+6. **Architecture is names only**: "Architecture" section contains expert name, one-line purpose, and role (executor/verifier) per expert. No deliverables, no constraints, no implementation details.
