Three correctness fixes on top of the m1 schema migration:
1) Fix the drainForMember claim-then-push race
----------------------------------------------------------------
Previously the claim CTE set delivered_at = NOW() *before* the WS
send. If readyState !== OPEN at push time, the row was marked
delivered and the message dropped silently — at-most-once with no
retry hook.
The new flow:
- claim sets (claimed_at, claim_id, claim_expires_at = NOW()+30s)
- delivered_at stays NULL until the recipient acks
- re-eligibility predicate now also accepts rows whose lease
expired, so dropped pushes redeliver (at-least-once)
Adds two helpers:
- markDelivered() — scoped to (mesh_id, recipient pubkey) so a
peer can only ack its own messages
- sweepExpiredClaims() — clears expired (claimed_at, claim_id,
claim_expires_at) every 15s, wired into startSweepers
2) Accept `client_ack` from recipients
----------------------------------------------------------------
New WS message type handled in the dispatcher right after `send`.
Lookups by clientMessageId or brokerMessageId; either is fine. Until
the daemon (apps/cli, separate worktree) starts emitting acks, leases
will simply expire and re-deliver — which is the desired retry
behaviour.
3) Tag presence rows with `role`
----------------------------------------------------------------
handleHello (member-keyed, used by the long-lived daemon WS) →
role: 'control-plane'
handleSessionHello (per-Claude-Code session WS) →
role: 'session'
listPeersInMesh exposes the new field; the peers_list response
surfaces it. WSPeersListMessage type adds an optional `role` plus the
long-undocumented `memberPubkey`. CLI-side filter swap from peerType
to role lands in a follow-up worktree — that's why the CLI is
untouched here per the M1 spec.
Typechecks clean (apps/broker tsc --noEmit, packages/db tsc --noEmit).
Test suite needs a real DB so wasn't run in this worktree; existing
dup-delivery and broker tests use drainForMember positionally and the
new claimerPresenceId arg is optional, so they should continue to pass.
