+fix(cli): `os migrate plan` / `apply` no longer run the app's `onEnable` or a host plugin's post-declaration hooks during their boot
+
+Clause-②: yes (widening)
+
+The two schema commands boot the host's stack to read what it declares. That boot ran the
+config's `onEnable`, and every `kernel:bootstrapped` / `kernel:listening` hook a host plugin
+registered from `init()`. A hook that reads a table the plan does not declare then failed on
+every plan. On `examples/app-crm`, whose `onEnable` binds positions to permission sets, each
+plan printed six `[sql-driver] DATABASE_ERROR` lines and six `position binding lookup failed`
+warnings, on a database `apply` had just migrated as well as on an absent one.
+
+The boot now composes host code for its declarations only:
+
+- `AppPlugin` takes a new `skipOnEnable` option. When it is set, `start()` does not run the
+  bundle's `onEnable`, logs that it withheld it, and reports it through `onEnableWithheld`. The
+  migrate commands set it on the app they compose from `objectstack.config.ts`.
+- A host plugin's `init()` gets a context that does not register `kernel:bootstrapped` or
+  `kernel:listening` hooks. The kernel contract defines those phases as work after registration
+  ends: reconcile/backfill, and opening listeners. `kernel:ready` hooks still run, and the
+  write guard still refuses their row writes. `kernel:shutdown` hooks and data hooks register
+  as before.
+- The plan's notes, and the `--json` payload's `composition.notes`, carry one line naming what
+  was not run.
+
+The plan itself is unchanged: the same tables, the same pending DDL, the same drift. `apply`
+still flushes the DDL the operator confirms and still runs the coverage pass. The platform's own
+plugins are untouched, so the value-shape gate announcement still prints.
+
+`@objectstack/runtime` widens its public surface, additively: `AppPlugin`, exported from the
+package root, gains the optional constructor option `skipOnEnable` (default `false`) and the
+read-only getter `onEnableWithheld`. A composition that does not pass the option gets exactly
+the behaviour it had, `onEnable` included.

+ * #21054 — a plan's declaration boot runs no app lifecycle hook.
+ *
+ * `examples/app-crm` measured it: its config's `onEnable` hooks
+ * `kernel:bootstrapped` and reads `sys_position` / `sys_permission_set`,
+ * tables the plan's composition never declares. Every plan — on a database
+ * `apply` had just migrated, and on one that does not exist — printed six
+ * `[sql-driver] DATABASE_ERROR` lines and six `position binding lookup failed`
+ * warnings. The write guard could not help: the hook only READS.
+ *
+ * The fixture is that shape, built here rather than read from
+ * `examples/app-crm` (a test reading another package's tree is an undeclared
+ * cross-package input): a stack with one object, a named `onEnable` export
+ * that hooks `kernel:bootstrapped` and reads the two undeclared tables, and a
+ * host plugin whose `init()` registers a reading `kernel:bootstrapped` hook
+ * beside a `kernel:ready` one.
+ *
+ * Pinned, in order: the POSITIVE CONTROL (the same code, composed the way a
+ * served boot composes it, prints the lines); `apply`'s confirmed work after
+ * the boot is unchanged (the DDL flush creates the app's table, the #13028
+ * coverage pass examines it); then the plan on the migrated file and on an
+ * absent one prints zero `DATABASE_ERROR` lines, runs neither hook, and still
+ * runs the host's `kernel:ready` hook.
