Stateless, task-oriented AI agent core

/**
 * PrepareTask's config-doors phase: the synchronous stretch from the
 * tool-face snapshot freeze through model/thinking/compaction-model resolution. The inputs are
 * exactly the fields of {@link PrepareConfigDoorsInput} (the original extraction slice — spec, deps,
 * sessions, the resume/internals seats); the outputs are the fields of
 * {@link PrepareConfigDoorsResult}, each one a value the slice defined and later phases consume —
 * re-verified as the complete "defined inside, consumed outside" closure at extraction time.
 *
 * ⚠️ SYNCHRONOUS FUNCTION, SYNCHRONOUS CALL — a hard constraint, not a style choice. This phase and
 * the safety scan after it run BEFORE prepareTask's first await (`sessions.acquire`), so a caller
 * has no microtask window in which to mutate `spec.tools`/the face arrays between the snapshots,
 * the doors and the scan. An `async` wrapper — even with a zero-await body — would hand the caller
 * exactly that window (the driver's `await` yields one microtask). Pinned by the
 * `prepare-task-phase-pins` microtask-latch tests.
 *
 * Throws pass through unchanged: every `config.*` / `resume_at.*` refusal here is a DELIBERATE
 * at-the-door rejection (a throw before acquisition needs no cleanup), and the
 * interaction-posture door's `deps.onError` disclosure (call order and payload) is part of the
 * contract. The per-task agents rebind returns a REBOUND spec (shallow copy, only `tools`
 * replaced) — the caller's object is never mutated; the safety scan must receive the rebound one.

 * Two refusals, both fail-loud (the {@link resolveStallTimeoutMs} posture: a bound nobody can evaluate is

 *  - **unknown key** ⇒ `config.limit_unknown_key`. TypeScript already rejects a stale key, but a wire /
 *    plain-JS caller does not go through TypeScript, and the retired names (`timeoutSec` above all) used
 *    to be honored — accepting them silently is how a caller keeps believing a limit is armed when the
 *    engine has stopped reading it.
 *  - **unevaluable numeric value** (non-number / non-finite / negative) ⇒ `config.limit_invalid`, naming
 *    the key. `0` is legal on every numeric axis: on `maxTurns` it is the documented "unbounded"
 *    sentinel, and on the budget axes it is an exhausted window (absurd but honest).

/**
 * Validate the MODE-VALUED members of `TaskSpec.attachments` at the same door, and return the
 * config unchanged. Today that is exactly one member, `totalTokensReminderMode`.
 *
 * WHY A DOOR AT ALL (坏值响亮度律): a knob whose bad value silently folds to the default is a knob the
 * deployment believes is armed. `totalTokensReminderMode: "padded_countdown"` (underscore) or
 * `"Countdown"` are the near-misses a hand-written config produces, and both would otherwise read as
 * "absent" and take the default arm — a DIFFERENT readout than the one that was asked for, with nothing
 * anywhere saying so.
 *
 * DELIBERATELY NARROW, twice over:
 *  - no unknown-KEY refusal (the `resolveTaskLimits` half that has no counterpart here): a wire caller
 *    that sends an attachment flag this engine does not know is asking for a lane that stays off, which
 *    is the family's own default posture — not a ceiling silently disarmed. Widening it would also be a
 *    behavior change for every existing caller, which this additive lane does not license.
 *  - the pre-existing `todoReminderMode` is NOT validated here. It has the same shape and the same
 *    weakness, but tightening it would refuse specs that run today; recorded as a follow-up rather than
 *    folded into this lane's change.
 *
 * A NON-OBJECT CONTAINER (`attachments: null` off a wire, above all) is neither refused nor crashed on
 * (verified by reading): every consumer reads this config through `attachmentsCfg?.…`,
 * so a null container already means "no lanes are wired" and the spec RUNS today. An unguarded property
 * read here — the first cut — turned that running spec into an untyped `TypeError` from inside a door
 * that promises a typed `config.attachment_invalid`, and refusing it instead would newly reject a spec
 * that works. There is no container-shape door in this family yet; that is a separate widening, not
 * something this lane gets to invent on the way past.
 *
 * The bypass is narrowed to values that CANNOT supply attachment fields: a
 * plain-JS caller can hand this a FUNCTION carrying `totalTokensReminderMode` as a property, and every
 * downstream `attachmentsCfg?.…` read would happily find it — so skipping a function here would fold a
 * typo'd mode to the default through exactly the hole this door exists to close. Functions are
 * property-bearing containers and are validated like objects; only `null` and primitives pass through.
