Delete the controller's own composition: planFor, declarationWith, renderingFor, grantsFor, theRestOfTheMesh, generators, whoResolves and composedAndValidated, with what only they reached (issue 1389)

Browse Source 
Every caller composes through mesh-sdk's go/compose since issues 1386 to 1388; the controller's second copy of the composition is dead code. The parent of this commit is fb556d6b, whose try (build-1792493691274712799, 17m28s, 2026-10-20 11:12 UTC) ran the equality test green on the live facts: every machine was sent and compared both ways (ADR 0453, issue 1384).

Deleted, 40 functions: in plan.go planFor, declarationWith, renderingFor, grantsFor, theRestOfTheMesh and their helpers (boundOfGrant, busCredentialIssued, carriedBuilds, carriedOn, composeBusUsers, engineJudgesRoot, engineReadsHealth, engineTakesHanded, takesHanded, givenUnderAnOldKey, issuedToHolder, keyFor, licencesFor, managerPublicKeyFor, movedProvider, providerMoved, providerModuleOf, sayLeftOut, seatsOn, wireBuilds, zonesInTheMesh); in network.go generators, whoResolves, namesInTheMesh, onThePrivateNetwork; composedAndValidated, adoptionFor, adoptionOf, engineOpensVaultBox, namedModules, localNetworksOf, keepRecorded, passSeatsOn, theMeshPassesSeatsOn, assignmentsOf. Choosing (Reading, Allocating, Foreseeing) is gone: coreBoxesFor and coreBoxesOf take a plain allocating flag. composeForPush no longer takes the private network it ignored. The seat pass of a send is performSeatPasses, over the passes the composition names.

Measured: cmd/mesh-controller non-test code 67,643 -> 65,821 lines (-1,822), its tests 57,691 -> 57,286, with the integration part of the equality test removed here because it calls the deleted functions. Not the issue's 3,000: that counts all of plan.go (2,192 lines), of which the callers, the verbs, the perform step and the sends remain (sendable, recorded builds, the held-back and ready-node logic, the plan verb, the gate's trial); and the 37 functions a name walk lists as unreachable are called through interfaces and method sets and are kept.

Tests dropped, each with the mesh-sdk go/compose test that holds its cases:
- seat_pass_test.go TestACompositionWithTwoClaimantsRecordsNoneAndSaysSo, TestACompositionChangesNothingWhileTheHolderIsAssignedOrNobodyClaims, TestAHolderAssignedButNotOnTheShelfIsNotTakenForGone: rest_test.go TestNoSeatIsPassedForTwoClaimantsAnAssignedHolderOrNoClaimant, TestAHolderAssignedButNotOnTheShelfIsNotTakenForGone, TestASeatWhoseHolderIsAssignedNowhereGoesToItsOnlyClaimant. TestACompositionPassesTheSeatAndWritesOneHandActByTheController and TestALostPassWritesNoActAndAFailedOneLeavesTheRecord stay as tests of the send's step (performSeatPasses); TestAThrowawayMeshPassesTheSeatInMemoryAndWritesNothing stays as TestAThrowawayMeshWritesNoHandActForAPass.
- seat_pass_test.go TestNoSeatIsPassedWhenAMachinesAssignmentsCouldNotBeRead: no counterpart, and none is needed: the adapter reads every machine's assignments for the Input and a machine whose read fails fails the Input, so no seat is passed on a partial read.
- network_test.go TestOnlyAMachineOnThePrivateNetworkIsNamed: network_test.go TestANodeNotOnThePrivateNetworkGetsNoAddressAndNoNetwork.
- held_back_test.go TestASendCarriesTheCurrentBuildsAndALeftOutModuleKeepsItsOwn: node_test.go TestAModuleLeftOutKeepsTheBuildItWasLastSent (and compose_sdk_test.go's table, now literal).
- modules_wire_test.go TestTheBuildOfACarriedCommitIsTheAssignmentsOrTheOneBuiltFromIt: node_test.go TestTheBodyCarriesTheOrderTheInputGivesAndTheBuildsOnlyToAnEngineThatReadsThem.
- compose_equal_integration_test.go: the old path it compares against is deleted; its last run is the parent's try.
Rewritten against mesh-sdk, same cases: issued_test.go (needs now come from compose.Resolve: Needed.IssuedToHolder and ProviderMoved), module_health_test.go and merge_gate_handing tests (the contract in the Input), provisioner_account_integration_test.go (the composition's refusal), one_resolution_integration_test.go (sayFound). Every test of the send, perform, the adapter and the verbs is kept; the tests that used planFor, declarationWith, generators, renderingFor or grantsFor as setup use resolveNode, composeSend, composeQuestion, renderingOf and grantsOf. compose_callers_test.go now fails when any deleted name is declared or called again.
