fix(stats): M6 — trekbrief and trekplan records land where the yardstick reads
New lib/stats/stats-append.mjs: one record on stdin, appended to
<data dir>/<kind>-stats.jsonl. The data dir is CLAUDE_PLUGIN_DATA, else
~/.claude/plugins/data/voyage-ktg-plugin-marketplace (the yardstick's
default). A failed write exits 1 with a reason: reported, never silent.
/trekbrief Phase 7 and /trekplan Phase 12 now run it instead of
"append to ${CLAUDE_PLUGIN_DATA}/…; skip silently". intent-approval's
resolveApprovalDataDir delegates to the same resolver.

Chose a stdin heredoc over a --json argument because a JSON record in a
shell argument breaks on quotes in task text. Only trekbrief and trekplan
are rewired (økt 2's countable form needs exactly those two); the other
commands' stats prose is unchanged and docs/architecture.md says so.

Red a358059 7/7 → green 7/7. Suite 1208: 1206 pass / 0 fail / 2 skip.

// lib/stats/stats-append.mjs
// Append one command-stats record to <data dir>/<kind>-stats.jsonl.
//
// Why this exists: the commands' stats phases said "append to
// ${CLAUDE_PLUGIN_DATA}/<kind>-stats.jsonl; if it is not set, skip silently".
// The Bash tool's env carries no CLAUDE_PLUGIN_DATA, so the record was skipped
// whenever the model did not guess the directory itself — the same silent skip
// that left brief-approved at 0 records. This writer resolves the directory
// the way scripts/yardstick.mjs reads it, and a failed write is REPORTED
// (exit 1 + reason), never swallowed. Stats still never block the workflow:
// the command prose reports the failure and carries on.
//
// CLI (the record is read from stdin, so no shell quoting of JSON):
// node lib/stats/stats-append.mjs <kind> <<'JSON'
// { ...record... }
// JSON
// → prints {"written":true,"path":...} exit 0 | {"written":false,"reason":...} exit 1
