A node-engine answers any verb of its own node, so a new engine verb needs no grants release (issue 774) #147

Issue 774 (L3). The bus refused every node-engine the new verb composition (and would refuse compose): buscompose engineGrants granted a fixed list from catalogue.EngineVerbs() compiled into the grants part's mesh-sdk pin (eff81f1), and every refusal made each engine drop and reopen its bus link (novox 3, ace 4 times in an hour). Second time of this kind (an earlier grants re-pin was needed for a new verb). Now a node-engine is granted mesh.seat.node-engine.tool.. (so call...) and event..: its own node only (one NATS token), callers still granted one verb at a time; a new engine verb needs no grants release. ADR 0563 §1, §3 and ADR 0259 §3 say nothing against it. Group fix/engine-seat-any-verb / fix/grants-any-engine-verb, merge order mesh-sdk first; mesh-grants pins mesh-sdk 748543c exactly (go.mod/go.sum only).

Quick vs thorough: quick = re-pin the grants part (needed again for every verb); thorough (chosen) = the per-node wildcard. The engine-seat subtest in buscompose_test gained composition, compose, a later verb and event, each on its own node only, and another node refused. gofmt, vet (both tags), go test pass.

Grant a node's engine any verb and event of its node seat on its own node, so a verb added to the contract needs no grants release first (issue 774)

748543c35f

The grants part composed the engine's subscriptions from catalogue.EngineVerbs at its own mesh-sdk pin, so mesh-host #184's optional verb composition was refused on every node and every engine reopened its link every four minutes. Quick fix: re-pin the grants part. Thorough fix (this): the seat's subjects on the engine's node, any verb, as a module answers mesh.mod.<module>.tool.>; callers stay granted per verb.
