fix review findings: stale seam docs + race-free doneFor test helper

Browse Source 
Codex review of the PR2 diff caught doc/comment sites doc-sync does not gate
(core-data-structures prose) and a latent test-helper race:
- docs/core-data-structures/persistence.md + bash.md, sqlite README, and two
  source comments (coordinator.ts, jsonl.spec.ts) still listed the removed
  has/delete/get/list methods — updated to the surviving four-method
  persistence surface and the get/list-free bash seam.
- doneFor(ctx, id) attached its onTaskDone listener lazily, after the task
  could already have closed (e.g. `true`), so it could miss the completion and
  hang. Replaced with trackCompletions(ctx): one eagerly-installed listener
  (mounted in setup() before any task starts) records every completion, and
  doneFor resolves immediately for an already-finished task or on completion
  otherwise. Race-free, and there is no get-by-id seam left to poll instead.

`BashExecutor` (`ctx.bash`, abstract — defined in [`packages/bash/bash/src/index.ts`](../../packages/bash/bash/src/index.ts)) mirrors the `LlmService`/`LlmAdapter` split: `resolve` (request → spec), `run` (foreground), `start` (background), `get`/`ownerOf`/`list`/`readOutput`/`kill`, and `onTaskDone` (a `BashTaskListener` completion callback). Spawned commands get a **scrubbed env** (dropping `*KEY*`/`*SECRET*`/`*TOKEN*`) and spill files use a private 0700 dir with random names and owner-only opens — model output never gets the ambient environment or a predictable path.

The **durability seam** for the event log. [session.md](session.md) describes the in-memory `Session` — the append-only `SessionEvent` log that is the source of truth. This page describes how that log is made durable: the abstract `SessionPersistence` service, its backends, the flush checkpoint, crash recovery, and the metadata header that travels alongside the log.
The seam is a textbook [capability seam](../rfc/implemented/architecture/2026-06-13-capability-seams.md): one abstract service ([dsh-session-persistence](../../packages/session-persistence/session-persistence), `ctx.sessionPersistence`) defining create/append/load/list/has/delete over the existing `SessionEvent` — **no parallel persisted type** — and two interchangeable backends that pass the same `runPersistenceContract` suite. See the [session-persistence RFC](../rfc/implemented/architecture/2026-06-14-session-persistence.md).

Both implement the same abstract `SessionPersistence` (create/append/load/list over `SessionEvent`) and pass `runPersistenceContract`, proving the seam is genuinely backend-agnostic:
- **[dsh-session-persistence-jsonl](../../packages/session-persistence/session-persistence-jsonl)** — an append-only JSONL log per session with crash-safe atomic writes, the interrupted-turn crash recovery above, and a read/replay path.
- **[dsh-session-persistence-sqlite](../../packages/session-persistence/session-persistence-sqlite)** — `node:sqlite`, one row per `SessionEvent`. The row shape `(session_id, seq, type, time, data)` maps 1:1 onto the event, so there is no parallel persisted schema to keep in sync.
