Tom Boucher d8af61be44 fix(#2220): replace invalid mempalace mine --room with detect_room() staging (#2260)
* fix(#2220): replace invalid 'mine --room' with detect_room() staging approach

mempalace mine has no --room flag (only search does) — verified against
MemPalace 3.5.0 official docs (mempalaceofficial.com/reference/cli.html).
The headless capture path used --room, causing every headless/no-MCP run
to fail with 'unrecognized arguments: --room' and silently skip capture.

Fix: replace the flag with a staging-based approach that uses detect_room()'s
documented folder-path match — stage the artifact under a room-named subfolder
with a mempalace.yaml room taxonomy, then run 'mempalace mine <stage> --wing'.

Changes:
- skills/gsd-mempalace-capture/SKILL.md: headless staging instructions
- commands/gsd/mempalace-capture.md: same
- capabilities/mempalace/fragments/capture-problems.md: reference staging
- .gitignore: exclude .planning/.mempalace-stage/
- tests/mempalace-capture-headless-invocation.test.cjs: regression test
- Golden install parity fixtures + workflow-size baseline regenerated

* docs: backfill changeset PR number (#2260)

* fix: regenerate golden fixtures after next merge

MemPalace capability — contribution fragment.
Rendered into the execute:wave:post verifier prompt when `mempalace.capture_artifacts` is true.
Contributes DATA (capture instructions), not control flow. onError: skip — never fails a wave.
-->
### Capture problems → fixes (MemPalace)
**Gate first.** Read `.planning/config.json`. If `mempalace.enabled` is not `true`, or `mempalace.capture_artifacts` is `false`, **skip this entire section** and let the wave complete unchanged. (This contribution is only injected when the capability is enabled; the `capture_artifacts` check lets you turn capture off without disabling the rest of the capability.)
Otherwise — after verifying this wave, persist any *confirmed* problem→fix pairs into the palace so they are recalled in future phases. This is best-effort; if MemPalace is unreachable, skip silently — capture never fails a wave.
For each confirmed bug/issue resolved in this wave:
1. **Resolve the wing** (`mempalace.wing`, else `project_code`, else project dir) and target `room: problems`.
2. **Dedupe first.** Call `mempalace_check_duplicate` (interactive) before filing so re-runs don't create duplicate drawers.
3. **File the drawer verbatim.** Store the problem statement and its fix as a drawer in `room: problems` — interactive: `mempalace_add_drawer`; headless: stage the artifact under the `problems/` folder and run `mempalace mine` (no `--room` flag — see [CLI reference](https://mempalaceofficial.com/reference/cli.html); room assignment is via `detect_room()` folder-path match per the [mining guide](https://mempalaceofficial.com/guide/mining.html); use the same staging pattern documented in `gsd-mempalace-capture` Step 3). Include provenance (`source_file`, phase id).
4. **Mirror the KG fact** when `mempalace.mirror_kg` is on: add `(<bug>, fixed_by, <fix>)` with `valid_from` = the phase date via `mempalace_kg_add`.
5. **Mode awareness** (`mempalace.memory_mode`). Under `augment` the fact is an *additive* mirror alongside `.planning/graphs/`. Under `kg_backend`/`replace` the palace is the *authoritative* store for the fact; GSD still writes `.planning/graphs/` through its normal graphify, so an unreachable palace never loses it.
Captures are idempotent: deterministic drawer IDs + `check_duplicate` mean re-running the wave re-files the same content without duplication. On any error, skip and let the wave complete normally.
