feat(intent): /trekplan halts without an approved intent; the approval is stamped on both paths

Veikart steg 1, økt 1 av 2. The three holes measured in the grounds:
(1) ## Intent / ## Goal were only checked for existence, (2) no approval
marker existed, (3) brief-approved was emitted only on the auto path.

- lib/validators/intent-approval.mjs: --check / --stamp. The marker is
  intent_approved_hash (sha256 over normalized ## Intent + ## Goal) +
  intent_approved_at. Editing either section after approval → STALE.
- /trekplan Phase 1 (Read the brief, both --brief and --project): runs
  --check and HALTS on BRIEF_INTENT_NOT_APPROVED / _STALE / _INVALID with
  the remedy spelled out; an unrunnable check halts too.
- /trekbrief Phase 4h (before the Phase 5 fork, asked even in --quick):
  shows Intent + Goal verbatim, AskUserQuestion Approve / Revise / Leave;
  only "Approve" runs --stamp. --stamp emits brief-approved, so the manual
  (default) path records it; the auto path's own emission is removed.
  New mode /trekbrief --approve <project-dir> = Phase 4h alone.
- README, CLAUDE.md, command-modes, HANDOVER-CONTRACTS §Handover 1,
  jsonl-schemas (trekbrief-stats gains intent_approved).

Valgt ingen brief_version-bump fordi skjemaendringen er rent additiv (to
valgfrie felt) og kravet sitter i /trekplan — enhver produsents brief kan
godkjennes via /trekbrief --approve uten produsentendring. Valgt eget
--check-kall i stedet for et flagg på brief-validator fordi --brief-stien
i dag ikke kjører validatoren i det hele tatt; et nytt validatorkall der
ville også stoppe på andre feil. Valgt fallback-datamappe = målestokkens
(plugins/data/voyage-…) fordi CLAUDE_PLUGIN_DATA er tom i Bash-miljøet og
event-emits egen fallback er stille skip — slik ble brief-approved 0 records.

What the marker does NOT prove (module header, command prose, contract):
same user, same machine — any session can stamp. A trace, not a signature.

Suite 1183 → 1201 (1199/0/2). Mutants M1–M5 (stale check off, check
always valid, gate line removed, stamp emits nothing, no normalization)
each fell ≥ 1 test. yardstick unchanged: RED, 1 of 3 countable.

## Phase 4h — Intent approval (veikart steg 1)
`/trekplan` does not plan against an intent the operator has not approved
(it halts on `BRIEF_INTENT_NOT_APPROVED`). This phase is where that approval
is given. It runs on EVERY brief, before the Phase 5 manual/auto fork, so
both paths pass through it — and it is **asked even in `--quick` mode**; there
is no skip path and no default answer.
1. Show the operator the `## Intent` and `## Goal` sections of
`{PROJECT_DIR}/brief.md` **verbatim** — the exact text the approval will
bind to. Do not summarize them.
2. Ask via `AskUserQuestion` — one question:
**"Is this the intent /trekplan should plan against?"**
| Option | Effect |
|--------|--------|
| **Approve** | Stamp the brief (step 3). |
| **Revise first** | The operator states the change; edit `## Intent` / `## Goal` in `brief.md`, re-run the Phase 4g validator, then return to step 1. |
| **Leave unapproved** | Write nothing. `/trekplan` will halt on this brief until `/trekbrief --approve {PROJECT_DIR}` is run. |
3. **Only on an explicit "Approve"** — never inferred from silence, from an
earlier answer, or from a "looks good" in free text — run:
```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/validators/intent-approval.mjs --stamp "{PROJECT_DIR}/brief.md"
```
This writes `intent_approved_hash` (sha256 over the normalized `## Intent`
+ `## Goal`) and `intent_approved_at` into the frontmatter, and emits the
`brief-approved` lifecycle event. It prints JSON; if `stamped` is `false`
(e.g. `## Goal` is empty), report the `reason` and return to step 1. Editing
`## Intent` or `## Goal` afterwards makes the approval stale — `/trekplan`
halts until the operator approves the new text.
What the stamp does NOT prove: any session on this machine could run the
same command. It is a trace that this step ran against this text, not the
operator's signature (see the header of `lib/validators/intent-approval.mjs`).
Report:
```
Intent: {approved (sha256:…12 hex) | left unapproved — /trekplan will halt}
```
In `--approve` mode, stop after the report and print the next step:
`/trekplan --project {PROJECT_DIR}` (only if approved).
## Phase 5 — Auto-orchestration opt-in (if research_topics > 0)
**Skip this phase if research_topics = 0.** Proceed directly to Phase 6.

### Auto path
**Auto requires an approved intent.** If Phase 4h ended "Leave unapproved",
the auto chain would halt at `/trekplan` anyway — print the manual-path
output instead and stop.
Set `auto_research: true` in the brief's frontmatter (edit the file).
Emit the brief-approved lifecycle event so downstream observability sees
the pipeline kick off (consumed by `lib/stats/event-emit.mjs`):
```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/stats/event-emit.mjs \
--event brief-approved \
--payload "{\"project\":\"${PROJECT_DIR}\"}"
```
The `brief-approved` lifecycle event was already emitted by the Phase 4h
stamp — on both paths — so it is not emitted again here.
If `gates_mode == true`: pause here via `AskUserQuestion` —
"Auto-mode confirmed. Proceed to research now? (yes/no)". If the user

### Read the brief
**Intent approval gate (veikart steg 1).** Before anything is read for
planning, check that the operator approved THIS brief's intent. Runs for
`--brief` and `--project` alike; `--quick` does not skip it and there is no
override flag:
```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/validators/intent-approval.mjs --check --json "{brief_path}"
```
Exit 0 → continue. Any other exit → **halt** — do not read further, spawn no
agent, write no plan. Print each error's `message` and `hint`, then stop:
| Code | Meaning | What the operator does |
|------|---------|------------------------|
| `BRIEF_INTENT_NOT_APPROVED` | No approval marker (`intent_approved_hash`) in the brief | `/trekbrief --approve {project_dir}` — read `## Intent` + `## Goal`, answer "Approve" |
| `BRIEF_INTENT_APPROVAL_STALE` | `## Intent` or `## Goal` changed after approval | Same command — the approval covers the old text, not this one |
| `BRIEF_INTENT_APPROVAL_INVALID` | Marker malformed, or `## Intent` / `## Goal` missing or empty | Fix the brief, then the same command |
If the command does not print the JSON report (module not found, node
missing, an unresolved `${CLAUDE_PLUGIN_ROOT}`), **halt** as well and show the
raw error: an approval check that could not run is never a pass.
`trekreview` briefs are exempt (the check returns exit 0 for them). What the
marker does NOT prove — it is a trace that the approval step ran against this
text, not a signature: see the header of `lib/validators/intent-approval.mjs`.
Read the brief file and parse its frontmatter. Extract:
- `task` — one-line task description
- `slug` — slug for plan filenames
