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.
