🩹 fix: Restore the @librechat/api Build and Remove Legacy Code (#14808)
* 🧹 chore: Remove Dead Legacy Agent Controller

`_LegacyAgentController` has been unreachable since the resumable path became
the only route: it is unreferenced, unexported, and untested. It had also
drifted out of compilability against the live file — line 2009 called
`attachConversationCreatedAt(req, { userId, conversationId, isNewConvo })`
against the 3-argument signature declared at line 97, which would await
`undefined` and then throw dereferencing `resolved.createdAt`.

Keeping it was not free. It carried a third independent copy of the response
message-id wiring (`getReqData`, `onStart`, four `updateMetadata` calls), so
every change to how a generation identifies its response row had a dead third
site to keep in step, and no test to say whether it had been kept in step.

Removing the block leaves `createCloseHandler` and the `sendEvent`,
`clientRegistry`, `requestDataMap` and `handleAbortError` imports with no
remaining callers, so those go too. `AgentController` was a three-line
passthrough to `ResumableAgentController`; the real controller is now exported
directly, which also matches the `[ResumableAgentController]` prefix every log
line in the file already uses. `server/routes/agents/chat.js` binds the export
to its own local name and passes the same five arguments, so the route is
unchanged.

No behavior change: 379 lines removed, 2 added.

* 🩹 fix: Remove Duplicated Anchor Block Breaking the `@librechat/api` Build

`dev` does not build. `packages/api/src/agents/activityPhases/runtime.ts`
carries two byte-identical 98-line copies of the same block (former lines
516-613 and 614-711), so rolldown fails to parse it:

    [PARSE_ERROR] Identifier `AnchorFields` has already been declared

The duplicated block is the anchor-construction work from #14805:
`AnchorFields`, `laterDefinedIndex`, `foldedAgentIds`, `boundedAnchor` and
`mergeAnchors`. #14807 was squashed from a branch that predated #14805 and
re-included that commit, so both copies landed. Only the `type` produced an
error — the four function declarations simply redeclare.

This removes the first copy. The two blocks were verified byte-identical
before the cut, and the resulting file has no duplicate top-level
declarations, is missing nothing that #14805 introduced, and retains
everything new to #14807 (`ResolvedPosition`, `resolvePosition`).

Verified: `tsdown` builds, `tsc --noEmit` clean, `config/circular-deps.mjs`
green across all five graphs (it was reporting `✗ @librechat/api` purely
because the build it shells out to was failing), and the 68 tests in
`activityPhases/runtime.spec.ts` pass.

Carried here rather than in a separate PR because this PR's checks cannot go
green until it lands: the failed `packages/api` build cascades into e2e, MCP
list_changed, bombadil and the Docker image jobs.
