docs(notes): retire current-state references to the deleted build graph

Three notes stated tsconfig.build.json as present-tense fact; the
aggregates (tsconfig.host.json / tsconfig.client.json) now own the
explicit reference lists and the root solution owns the emit graph.
Historical narration in dated notes is left untouched.

 The package list had been enumerated in five places. The uniform depth-2 layout lets most of them be derived instead:
 
-- `tsconfig.base.json` maps every package through a single `@deepseek-ai/dsh-*` `paths` wildcard listing one candidate per group, in place of per-package entries. Root `tsconfig.json` reuses that source map and carries the explicit project references that keep package/vendor typecheck boundaries intact. (One subtlety this introduced: a path candidate contains `/*/`, which a naive regex comment-stripper mistakes for a block comment — `scripts/doc-typecheck.ts` reads the JSONC config through TypeScript's parser rather than stripping comments by hand for exactly this reason.)

 - Shared shape: entry `lib/types/index.js`, `outDir: 'lib'`, ESM, `platform: node`, `target: es2024`, `fixedExtension: false` (keeps `.js` for `"type": "module"` packages), `dts: false` (tsc -b owns declarations), `clean: false` (lib/ also holds TSC's `lib/types` intermediate tree). The entry was originally `src/index.ts`; the [TSC-first build Agent Note](2026-06-17-ts-build-config.md) later moved tsdown to bundling TSC-emitted JS so TypeScript transform behavior comes from one compiler.
 - Two per-package overrides in vendor/ (ours, like the regenerated tsconfigs; logged in vendor/README.md): schemastery (dual `.mjs`/`.cjs` via `outExtensions`), logger-console (two single-entry passes so the shared base class is inlined into each entry instead of a hash-named chunk, matching upstream's published shape).

 Package and gate inventories are repeated across TypeScript project references, package docs, CI prose, and Knip overrides. Most restate package layout, manifest data, or aggregate command contents. Each new package therefore creates avoidable synchronization points.
 
-The [package hierarchy](../../implemented/architecture/2026-06-20-package-hierarchy.md) already removed several of these by hand: `scripts/publint-all.ts` now derives its list from the `packages/<group>/<pkg>` layout, and the two `tsconfig` `paths` maps collapsed to one `@deepseek-ai/dsh-*` wildcard. What remains is the inventory that cannot be globbed away — chiefly `tsconfig.build.json`'s project `references`, which TypeScript requires as an explicit array (no wildcard form).

 Static lists are appropriate when they encode policy; they are needless friction when they duplicate manifest data or layout facts that already exist in `package.json`, workspace globs, or the package hierarchy.
 
 ## Proposal
 
-Make the remaining package/gate inventories discoverable. A single canonical source — the `packages/<group>/<pkg>` hierarchy plus package manifests — should drive `tsconfig.build.json`'s `references`, the module graph, and any other full-package list, with a generate-and-verify step (the existing `gen-module-graph` / `gen-cordis-catalog` pattern: a generator writes the artifact, a `--check` mode in `hygiene`/`doc-sync` fails on a stale committed copy). Module graph generation already reads package manifests. `doc-sync` should be the one command that defines and prints its sub-gates, with docs linking to that command rather than restating a second list.

 The hierarchy does not need to encode every fact about a package, but it should encode the broad maintenance policy: core/product packages, integrations, capability seams, and support/test/example packages should not all require a hand-maintained exception list before scripts can tell them apart.

 ## Acceptance criteria
 
-- `tsconfig.build.json` project `references` are generated from the hierarchy (a generator emits them; a `--check` gate fails when the committed copy is stale), rather than hand-maintained.

 - Adding a package does not require editing a static package list for any gate.
 - Docs describe the source of truth rather than repeating generated inventories.
 - CI invokes the aggregate commands and lets those commands own their sub-gate lists.
