Document the package hierarchy and finalize the RFC

Add a README to each group dir (core/llm/bash/session-persistence/ui/
support) stating its role and product-vs-support classification, and
rewrite packages/README.md around the hierarchy (group table, grouped
"what goes where", removed the package-hierarchy FIXME).

Move the package-hierarchy RFC to implemented/architecture/ and rewrite
it to describe what shipped (placement rationale, the paths-wildcard and
publint dedup, the two new guardrail gates). Fold the remaining
tsconfig.build.json references dedup into the discover-package-inventory
proposal and fix its cross-link.

Update AGENTS.md: regrouped repo-layout map, depth-2 globs, the new
verify-package-paths gate in the doc-sync listing, and a note that we
lean toward stricter lint in the agentic-coding era (machine-caught
errors and a consistent foundation outweigh the one-time cost).

## Problem
Package and gate inventories are repeated by hand. [scripts/publint-all.ts](../../../../scripts/publint-all.ts) has a static list of publishable packages. The [package cookbook](../../../cookbook/adding-a-package.md) tells authors to update several files. The [package README](../../../../packages/README.md) carries a hand-written dependency graph. [CI](../../../../.github/workflows/ci.yml) and [development docs](../../../development.md) can drift from the actual `doc-sync` subcommands when new gates are added. These lists are small today, but every new package or gate creates another manual synchronization point.
Package and gate inventories are repeated by hand. The [package cookbook](../../../cookbook/adding-a-package.md) tells authors to update several files. The [package README](../../../../packages/README.md) carries a hand-written dependency graph. [CI](../../../../.github/workflows/ci.yml) and [development docs](../../../development.md) can drift from the actual `doc-sync` subcommands when new gates are added. `tsconfig.build.json` lists all 18 packages as explicit project `references`. These lists are small today, but every new package or gate creates another manual synchronization point.
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 package/gate inventories discoverable. Publishability should come from the deliberate [package hierarchy](../architecture/2026-06-20-package-hierarchy.md) plus package manifests, not from a static array in a script or the npm `private` flag. Module graph generation should read 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.
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
- `publint-all` discovers publishable packages from the hierarchy plus manifests instead of a hard-coded array.
- Adding a package does not require editing a static package list for every gate.
- `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.
