Phase 4-lite C4 — the headline declarative path. An app's manifest can now bind
a `[[routes]]` / `[[triggers]]` to a script it does NOT declare, resolving the
name to an inherited group-owned endpoint on the app's chain (nearest-owner
wins; an app's own script of the same name still shadows it — CoW).
* `resolve_inherited_targets(app_id, bundle)` resolves every route/trigger
target name that isn't an app-own manifest script to a group endpoint via
`get_by_name_inherited`, returning `name → script_id`. Run once before the
apply transaction (group scripts pre-exist, committed).
* `validate_bundle` takes the inherited endpoint names so "binds to unknown
script" / "is a module" checks pass for inherited targets.
* The apply transaction merges the inherited targets into `name_to_id`
(app-own keeps precedence), so route/trigger inserts bind to the group
script's id.
* `compute_diff_with_inherited` adds the inherited ids → names to the diff's
name map, so a route bound to a group script resolves its name and
re-apply is idempotent (without this it read as a perpetual rebind).
Live-validated: an app under group G with a manifest binding `GET /greet` to
the group's inherited `greet` plans as `route create → greet` (no script
create), applies (+1 route, +0 scripts), and re-plans as `noop` (idempotent).
