improve: doctor migration checks no longer load every bundled plugin runtime (#120678)

* perf(plugins): declare doctor contract surfaces

* perf(doctor): slim migration import closures

* perf(plugins): narrow doctor declaration record surface and wire owner-test lane

Registry records carry only the doctorContract declaration instead of the whole
parsed manifest, and check:changed now selects the src/plugins-owned declaration
honesty and closure-guard tests for extension module/manifest changes so
cross-lane drift cannot pass PR classification.

* fix(doctor): keep control-plane dist imports require-safe

Keep doctor and channel control-plane chunks off exec-class dependencies, and enforce native require(esm) loading during postbuild.

* chore(plugin-sdk): regenerate API baseline

* chore(plugin-sdk): sync export ordering

* fix(plugins): satisfy doctor contract CI boundaries

* perf(doctor): make qqbot doctor closure dependency-light

qqbot was the last plugin above 5s in doctor state-migration enumeration
(~8s under tsx/jiti). The cost was not the state-key builder (already a
leaf): its doctor closure value-imported the runtime-doctor SDK barrel,
whose plugin-state-store/state-db re-exports pull kysely (~330 modules),
plus security-runtime for one fileExists (~200 modules), all resolved
per-module by jiti during enumeration.

Split the migration-define helpers and light re-exports into a new
private-local plugin-sdk/runtime-doctor-migrations subpath; runtime-doctor
re-exports it so its public surface is byte-identical (API baseline hash
unchanged). qqbot's doctor-contract and state-migrations now import only
the light subpath, swapping fileExists for the equivalent async
legacyStateFileExists already in the closure.

qqbot enumeration: ~8.0s/531 modules -> ~0.25s/18 modules.

* chore(plugin-sdk): drop private-local subpath from API baseline

runtime-doctor-migrations is private-local-only; the baseline tracks public
modules, and the earlier line was generated before the classification.

* fix(plugins): register runtime-doctor-migrations boundary paths

The private-local subpath list feeds the extension package boundary map;
the shared paths config and xai's derived overrides must carry the same
entry or the boundary contract test fails.
