Tianyi Cui f7bd7e82d1 fix review findings: restrict export-import aliases to prose-only targets
Codex round-3: alias prose matches the gate's strength only when the
target's own contract is prose-only. An export-import alias to a
function, class, or namespace target (or an unresolvable one) is now
refused — those carry signature/member contracts the alias cannot
hold; export the declaration directly instead. Const/enum/interface/
type-alias targets keep the self-documentation contract.

Tests pin the refusal for function, class, and namespace targets;
module doc and RFC updated.

/**
* Verify JSDoc completeness for EVERY module-level exported name of every
* non-vendored package (each `packages/<group>/<pkg>/src/` tree). This is the
* mechanical form of the AGENTS.md rule "every export has a JSDoc explaining
* semantics", generalizing the cordis-surface gate (`gen-cordis-catalog.ts`,
* which owns `interface Events` members and `ctx.<key>` service classes) to
* the whole export surface; the parsing + check helpers are shared via
* `scripts/jsdoc.ts` so "documented" means the same thing on both.
*
* `tsx scripts/verify-export-jsdoc.ts` → exit 1 listing every offender
*
* The contract, per exported declaration kind:
*
* - Every exported name needs JSDoc with non-empty description prose (prose
* ends at the first block tag, standard JSDoc semantics).
* - A function-like export (function declaration, a const with a function
* initializer or an INLINE callable annotation, or a non-identifier
* function default export) additionally needs a non-empty `@param` per
* parameter (`this` receiver annotations exempt; a stale `@param` errors)
* and a non-empty `@returns` unless the return type is `void` /
* `Promise<void>`. Wrapper expressions (parentheses, `as` / `satisfies`
* casts, non-null assertions) are peeled before classifying. The walk
* classifies returns syntactically, so the return type must be ANNOTATED —
* except a const whose declarator is annotated with a NAMED type (e.g.
* `export const f: Handler = …`), where that type's own declaration owns
* the signature contract and `@returns` stays optional; an inline
* `(x: T) => U` annotation or single-call-signature literal is the surface
* signature itself and gets the full contract, and a literal mixing
* call/construct signatures with anything else is refused (extract a named
* type).
* - An exported class needs class-level JSDoc; its public methods (static
* included — they are reachable on the exported name) follow the function
* contract, and public properties and accessors need description prose (on
* a get/set pair the getter's doc covers both). A member declared by an
* `extends`/`implements` heritage type is EXEMPT — the seam declaration is
* the doc's one home, the IDE inherits it, and re-documenting every
* implementation invites drift — UNLESS the override grows surface the
* base never documented: a protected-only base member does not exempt a
* public override, and parameters the base never names keep their `@param`
* duty. This is the one question the walk asks the TYPE CHECKER (heritage
* members live across package boundaries); everything else is pure AST.
* Constructors are exempt like the cordis gate's: plugin classes are
* framework-constructed, and the class doc owns the story.
* - Exported interfaces, type aliases, enums: description prose on the
* declaration (member-level docs stay review's job; the highest-value
* member surface — seam service classes — is already under the cordis
* gate).
* - An exported namespace recurses (its exported members are package
* surface; in an ambient `declare` namespace every member exports
* implicitly); the namespace itself needs prose only when it does not
* merge with an already-documented same-name declaration (the
* Config-namespace idiom documents the class/function once, not twice).
* - The cordis plugin-protocol slots are exempt: top-level `name` / `inject`
* / `reusable` / `Config` consts and the `apply` entry, plus the same
* slots as statics on a plugin class. Their shape is fixed by the
* framework, so a doc would restate the protocol — the module doc comment
* and the `interface Config` carry the plugin's real semantics. (These
* names are reserved by cordis convention; documenting one anyway is
* allowed, only absence goes unchecked.)
* - Overload groups: each overload signature carries its own docs; the
* implementation signature is exempt (callers never see it).
* - Skipped: `declare module` / `declare global` augmentation bodies (the
* cordis gate's turf; an augmentation is not an export of the package) and
* re-export statements with a module specifier (`export … from`) — the
* defining module is walked on its own, and external definitions are not
* ours to document. An `export import X = N.member` alias documents
* ITSELF, and only prose-only target kinds are gate-supported: a callable,
* class, or namespace target carries signature/member contracts the alias
* cannot hold and is refused (export the declaration directly).
* - Everything else fails CLOSED: `export =` is refused outright, and an
* exported statement kind the dispatch does not recognize is itself a
* violation, so no export form can pass unchecked by omission.
