fix(#3128): extend roadmap.cjs plan-count to detect {N}-PLAN-{NN}-{slug}.md layout (#3139)

* fix(#3128): extend roadmap.cjs plan-count to match {N}-PLAN-{NN}-{slug}.md

Root cause: same regex flaw as #2893 (fixed in phase.cjs by #2896).
The manager-dashboard countPhasePlansAndSummaries() in roadmap.cjs was
not updated alongside the phase.cjs fix. Files like 5-PLAN-01-setup.md
end in -setup.md, not -PLAN.md, so plan_count returned 0.

Symptom: init manager returned plan_count=0 / disk_status=discussed for
fully-planned phases, triggering redundant background planner agents that
correctly detected existing plans and declined -- wasted runs.

Fix: apply the same looksLikePlanFile pattern from phase.cjs with
PLAN-OUTLINE and pre-bounce exclusions to countPhasePlansAndSummaries.

Regression test: tests/bug-3128-roadmap-plan-count-slug-layout.test.cjs
Suite: 6985/6985. Closes #3128.

* fix(lint): allow-test-rule for roadmap isPlanFile structural contract test

+**`roadmap.cjs` plan_count now correctly detects `{N}-PLAN-{NN}-{slug}.md` files** — the manager-dashboard plan-count filter matched only `*-PLAN.md` and `PLAN.md`, missing the slug-form layout (`5-PLAN-01-setup.md`) that `gsd-plan-phase` actually writes. `init manager` returned `plan_count: 0` / `disk_status: "discussed"` for fully-planned phases, causing the manager to recommend and dispatch redundant background planner agents. Same regex flaw as #2893 (fixed in `phase.cjs` via PR #2896); `roadmap.cjs` was missed in that sweep. Fix applies the same `looksLikePlanFile` logic (with `PLAN-OUTLINE` and `pre-bounce` exclusions) to `countPhasePlansAndSummaries`. Closes #3128.
