Two gaps found via audit against Shipyard's source:
1. Stage 6/7 still said "this agent does not exist yet" and told a
driving session to treat any lane reaching those stages as blocked —
stale since E3 shipped qc-local + senior-gate-reviewer. Replaced with
an unconditional launch plus a one-time "ccam lanes agents install"
preflight note in Setup.
2. Stage 12's conflict-resolution path called `ccam lanes sync-base`
directly on any CONFLICTING PR, with no check that the PR's base is
actually `development` first. Shipyard's original has this guard
(its own "legacy main-based PR" case) — ported here in general form:
never auto-merge into a PR whose base drifted from `development`.
