The pools were config-only until now: the launchers still received one global
effectiveDefaultProfile and placement still ranged over every configured
profile, so a reviewer could be placed on an architect-only backend.
Three parts:
SessionManager computed the role, stored it on the MemberSession, and never put
it on the SpawnRequest. So the role reached the record that describes the spawn
but not the call that performs it — every launcher saw DEV. Both spawn paths
(plain and worktree) now carry it.
CompositePeerLauncher takes the Fleet and draws its candidates from
fleet.<role> instead of from all profiles. An absent or empty pool means
unconstrained, not blocked: a config that declares pools for some roles must
keep spawning the rest, so it falls back to every profile. A null Fleet is the
pre-CB-557 wiring and behaves exactly as before.
Bridged passes cfg.fleet() to the composite and cfg.fleet().tabLabel() to both
launchers. The tab-label knob was accepted by HerdrPeerLauncher but passed by
nobody, so it was inert — the label only looked right because the fallback
happened to match the configured template. Four tests now pin the wiring
instead of the coincidence.
An EXPLICIT profile stays exempt from the pool. `bridge_spawn{profile:"opus"}`
carries no role, so it defaults to DEV; judging it against the dev pool would
refuse a spawn the operator asked for by name. maxLoad still applies to it.
Also cleared the IDE warnings in the touched files: an immediately-rethrown
catch (the comment stays, the redundant block goes), unused lambda params, a
javadoc link to a package-private class, two unused imports.
601 tests pass.
