docs: generate each subsystem's cordis surface into its own page; delete the flat catalogs

Browse Source 
Rebuild of the region machinery (PR3) on the post-#904 Typert projection:
renderPageRegion/renderInheritedPage live in dsh-typert-generator beside the
projection; scripts/gen-cordis-catalog.ts owns the curated SERVICE_PAGE /
EVENT_SCOPE_PAGE / SERVICE_WALK_EXEMPTIONS / LINK_MAP partition (fail-loud in
both directions, with the independent Context-merge scan backstopping the
projection's blind spot), spliceRegion, and the guarded pair auto-record.
docs/cordis-catalog/ is deleted: the flat events/services catalogs dissolve
into per-page regions and docs/cordis-catalog/core moves to docs/cordis-api/
with the inherited tier as its own generated page. The partition absorbs the
post-regrouping surface: ctx.typert → invariants.md, ctx.directoryPicker →
workspace.md, skills/* events → skills.md, and the four launcher-provided tui
accessor values join the named exemptions.

- **Delegation depth** is durable `SessionHeader.delegationDepth` plus the merge-extensible runtime field `AgentOptions.subagentDepth`; absence means top-level depth zero, and the greater present value is authoritative. The seam owns both fields — the loop neither sets nor reads them — so an in-process child persists parent depth + 1, cold resume cannot lower it, and every start rejects a derived depth outside the safe-integer domain or above a defined absolute `request.maxDepth` cap.
- **Fork seeding** uses `CreateAgentOptions.seed` (a `SessionEvent[]` prefix threaded through `AgentLoop.createAgent` → `ctx.sessions.prepare({ seed })`, the same primitive `ctx.agents.resume()` uses). The fork backend passes a *balanced completed-turn prefix* of the parent's log — the parent's events up to and including its last `turn/end` — so the seed is contiguous-from-0 and the [invariants](../../packages/support/invariants) replay accepts it (the in-flight, unbalanced turn is excluded).

## Cordis surface
Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — this section is byte-identical in both language sides of the page. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.md#dispatch-modes), and the framework-inherited `ctx` surface lives in [cordis-api/inherited.md](../cordis-api/inherited.md).

Named provider registry with one-shot runs, durable discovery, and continuable-child operations.
```ts cordis-catalog
/**
* Establish one durable continuable child and deliver its initial prompt.
* Resolves when the child's inbox accepts that prompt, without waiting for the
* turn to start or for the message to reach the Session log; any earlier
* failure rejects with no ids and rolls back the child entirely.
* @param spec - provider, delegation request, and caller cancellation.
* @returns the durable child id and the accepted prompt's message id.
* @throws when continuation services are unavailable or materialization fails.
*/
async startContinuable(spec: ContinuableStartSpec): Promise<ContinuableStart>
/**
* Deliver one later message to a continuable child as its next FIFO turn. A
* resident child's Agent inbox accepts it directly (waking a `waiting`
* Activation), while an absent one is cold-resumed from its persisted
* Session. The Agent inbox is the only queue, so every accepted message has
* one observable order.
* @param parent - the exact live direct parent authorizing this delivery.
* @param childId - durable child session id.
* @param content - user-role content to deliver.
* @param options - durable provenance and caller cancellation, which stops the
* operation only before inbox acceptance.
* @returns the accepted message's inbox id.
* @throws when continuation services are unavailable, parent authority is
* rejected, or the message was not admitted.

* signal is issued before this returns, but the target may keep running
* until it observes the signal. Unclaimed pending inbox work, the Activation,
* and published descendants are preserved; claimed work is not requeued.
* Once the interrupted driver is idle, a waking send resumes the parked FIFO
* queue. An absent target — including a one-shot or unknown id —
* is an accepted no-op, as is a manager-less composition, which cannot own a
* live Activation.

* session store with optional session persistence (live-preferred) and
* serves each child's durable mode/label from the registered `subagent`
* projection unit down a three-rung ladder — the registry's watermark
* snapshot for a live child; for a cold one, a durable projection-cache
* row when the optional cache serves an own-suffix identity (its `seq`
* gate proves the value postdates the fork seed, where a child's own
* descriptor is immutable once appended), else one persistence inspection
* folded through the registry. The
* projection fold is the single classification authority; per-child
* diagnostics relay a fold that served no identity or a failed inspection,
* never a list-time descriptor parse. Absent persistence, enumeration is
* live-only (a cold child cannot be resumed then either, so its absence is
* capability absence, not an error). This service consults no Agent
* registrations, Activations, or providers.
*
* Every persistence read receives `signal`, and the listing rechecks
* cancellation around each of those awaits. Read rejections that settle
* after an abort become a stable `SubagentError` with code `CANCELLED`.
* @param parentSessionId - parent session whose direct children are listed.
* @param signal - caller-owned cancellation forwarded to persistence reads
* and observed around every read await.
* @returns children and per-child diagnostics ordered by `createdAt`, then id.

* store is not mounted, or the caller cancels the listing.
