Add the deterministic, unit-testable core of the gate-migration and
coordinated-release slice (amicode#1083):
- SessionRollout.Capability.discover — a versioned {protocol_version,
mode, migration_boundary} object; full/partial/legacy resolved from
engine support + the session root's persisted mode + epoch marker,
without probing a mutation route. protocol_version reuses the #1077
registry generation. A rollback gate (fullDiscoveryEnabled) caps full.
- SessionRollout.Matrix.resolve — the supported mixed-version matrix
(old-engine+new-client -> legacy; new-engine+old-client -> pre_ledger
view; new+new -> full only for a full root, else labelled partial/legacy).
- SessionRollout.Migration.startEpoch — legacy -> partial ONLY via an
explicit epoch start (no infer/backfill path exists).
- SessionRollout.resolveReservation — in-flight v1 reservations resolve
as legacy, never adopted into a ledger op.
- SessionRollout.Rollback — the disable-full-before-withdraw-routes
ordering invariant, so no uncontextualized full-provenance mutation.
- SessionRollout.Release — manifest parse + all-required-passed readiness
evaluator + fork->binary-pin->extension ordering evaluator. Reads a
manifest and reports readiness only; default enablement stays off and
NO release act is performed (those are human-only).
40 focused tests green; package tsgo typecheck clean. Release-execution
acts (tag/pin/publish/overlay-sync/enablement flip) are human-only and
intentionally out of this slice.

Implements the testable code portion of harmoniqs/amicode#1083, part of #972.
HITL — READY FOR HUMAN REVIEW, not auto-merged.
Deterministic capability discovery, mixed-version matrix, migration boundary, in-flight reservation resolution, rollback safety, and the release-manifest readiness evaluator (default-enablement stays OFF).
HUMAN-ONLY, NOT done here: tagging the fork release, verified binary pin, extension publish, overlay sync, and the default-enablement flip. #1084 fills the matrix-case seam the evaluator reads.
