feat(#1165): async external_job_waiting half-state + resume/pause contract (#1221)

Core half of #1105: a legal external_job_waiting deferred state so an async-dispatched Execute step (committing a .planning/async-jobs/<job>.json manifest, deferring SUMMARY.md) is not an illegal partial. execute-phase safe-resume, resume-project, and pause-work reconcile against the versioned scheduler-agnostic manifest stability contract without re-dispatching; the producer is the capability half (#1164). Closes #1165.

**Async external jobs can now defer an Execute step legally (`external_job_waiting`).** An Execute step that dispatches a long-running external job and commits a `.planning/async-jobs/<job>.json` manifest — deferring `SUMMARY.md` — is now recognized as a *legal deferred state*, not an illegal partial-plan state. `execute-phase` safe-resume, `resume-project`, and `pause-work` reconcile against the manifest instead of re-dispatching (which would duplicate the external compute). This defines the versioned, scheduler-agnostic manifest **stability contract** consumed by the core loop; the scheduler adapter that *produces* manifests is the capability half (#1164). (#1165)

### ESLint harness
The canonical lint infrastructure adopted in ADR 452 (`docs/adr/452-eslint-lint-harness.md`): ESLint flat config (`eslint.config.mjs`) with `typescript-eslint`, `eslint-plugin-n`, `eslint-plugin-no-only-tests`, and a local AST-rule plugin at `scripts/eslint-rules/`. Replaces the homegrown `scripts/lint-*.cjs` regex scanners. The three custom test-rigor rules (`local/no-source-grep`, `local/no-magic-sleep-in-tests`, `local/no-elapsed-assertion`) initially ship at `warn`; they become `error` after the cleanup sweep tracked at issue #453 merges.
### External-job-waiting half-state
A legal deferred state of an Execute step (`external_job_waiting`): the executor has dispatched a long-running async external job and committed an async-job manifest at `.planning/async-jobs/<job>.json` instead of a SUMMARY.md. Distinct from the synchronous "mid-production-commits" half-state and from an illegal partial-plan state. The core loop's step-completion + safe-resume/pause contract treats a non-terminal manifest as legal and reconciles against it (never re-dispatching the plan, which would duplicate the external job); SUMMARY.md is deferred until the job reaches a terminal state and its `expected_artifacts` are verified. The manifest is a versioned stability contract (`docs/reference/planning-artifacts.md`); core *consumes* it while a default-off scheduler-adapter Capability (#1164) *produces* it at `execute:wave:post` — the contract-is-core / producer-is-capability seam mirrors ADR-857's verification-substrate decision. Status enum is closed and scheduler-agnostic: `submitted`, `running`, `completed-unverified`, `failed`, `cancelled`, `timeout`.

### `.planning/async-jobs/<job>.json`
**Purpose**: Durable manifest for an async external job dispatched during Execute (long-running compute, e.g. HPC solver/training jobs). Its presence makes an Execute step's SUMMARY-absent state a *legal* `external_job_waiting` deferral rather than an illegal partial-plan state.
**Stability contract (Hyrum's Law).** This schema is a depended-upon interface across the core loop and every scheduler backend. The core loop consumes only the named fields below and ignores any others; producers MUST write these fields and MAY add their own. The `version` field is the escape hatch for evolving the schema without breaking consumers. Coordinate any change with both the core half (#1165) and the producer capability (#1164).
**Produced by**: a scheduler-adapter Capability at the `execute:wave:post` loop extension point (the capability half — tracked in #1164, default-off). Core never writes this file.
**Consumed by**: `execute-phase` safe-resume, `resume-project`, and `pause-work` (the core half — #1165).
| Field | Type | Meaning |
|---|---|---|
| `version` | string | Manifest schema version (`"1.0"`). |
| `job_id` | string | Backend-assigned job identifier. |
| `plan_id` | string | `<phase>-<plan>` this job belongs to — the key tying the job to its Execute step. |
| `phase` | string | Phase number. |
| `backend` | string | Scheduler/backend name (e.g. `slurm`). **Opaque to core** — core never interprets or invokes it. |
| `submit_command` | string | Exact command used to submit the job (audit / resubmit). |
| `status` | enum | Scheduler-agnostic lifecycle state (see below). |
| `expected_artifacts` | string[] | Paths the job is expected to produce; verified before the plan is closed. |
| `verification_command` | string | Command that verifies the job's output before close-out. |
| `resume_command` | string | Exact command to resume GSD reconciliation (re-enter the loop to re-check the job), e.g. `/gsd:execute-phase <phase>`. This is a GSD reconciliation entry point, not a scheduler resubmit. |
| `submitted_at` | string | ISO 8601 submission timestamp. |
| `terminal_details` | object \| null | Failure/terminal-state detail; `null` while non-terminal. |
**`status` enum** — closed and scheduler-agnostic; producers map backend states onto these, and core reads only these:
- `submitted`, `running` — **non-terminal**. The plan is in the legal `external_job_waiting` half-state; resume re-checks and never re-dispatches the plan.
- `completed-unverified` — job finished but output not yet verified; resume MUST verify `expected_artifacts` / run `verification_command` before writing SUMMARY.md and closing the plan.
- `failed`, `cancelled`, `timeout` — **terminal failure**; resume surfaces `terminal_details` and offers recovery: re-run reconciliation (`resume_command`), abort, or mark-and-skip. Resubmitting compute is a Capability/user action, never an automatic core action.
**Trust boundary — manifest commands are untrusted input.** The manifest crosses a trust seam: a Capability (or anything that can write `.planning/`) produces it; the core loop consumes it. `submit_command`, `verification_command`, and `resume_command` are therefore UNTRUSTED. The core loop MUST NOT auto-execute them — before running any manifest-sourced command, surface the exact command and its manifest path to the user and require explicit confirmation. Validate before trusting a manifest: `version` is a recognized schema version, `plan_id` matches the plan under reconciliation, and `status` is one of the closed enum values. If a manifest is malformed or unrecognized, surface the anomaly and stop rather than acting on it.
**Matching, multiple, and malformed manifests.** Match a manifest to a plan by its exact `plan_id` (string-equal — phase ids may contain `.`). If more than one manifest matches a single `plan_id`, or a matched manifest is not valid JSON, fail closed: surface the conflict and stop; never pick one heuristically.
**No auto-dispatch (duplicate-execution guard).** A plan whose `plan_id` matches a manifest (any status) is excluded from EVERY dispatch path — `execute-phase` `safe_resume_gate`, `execute-phase` `discover_and_group_plans` (normal and cross-AI), and `execute-plan` plan-selection. Never spawn a fresh executor for such a plan; reconcile instead. Re-dispatching would duplicate the external job.
**Matching a manifest to a plan** (glob-safe — tolerates an absent directory):
```bash
ASYNC_MANIFEST=$(find .planning/async-jobs -maxdepth 1 -name '*.json' -exec grep -lE "\"plan_id\"[[:space:]]*:[[:space:]]*\"${CURRENT_PLAN_ID}\"" {} + 2>/dev/null || true)
```
Match by exact `plan_id`. If more than one manifest matches, or any matched manifest is not valid JSON, fail closed: surface the conflict and stop.
**Reconciliation by status** (manifest commands are untrusted — surface + require explicit user confirmation before running any):
- `submitted` / `running` → non-terminal; still waiting. Report the job and stop; resume later. Never re-dispatch.
- `completed-unverified` → after confirmation, verify `expected_artifacts` / run `verification_command`; only on success write SUMMARY.md and close the plan. If artifacts are missing, surface the anomaly — do not close.
- `failed` / `cancelled` / `timeout` → terminal failure; surface `terminal_details` and offer recovery (re-run reconciliation via `resume_command`, abort, or mark-and-skip). Resubmitting compute is a Capability/user action, never automatic.
