Tom Boucher a375c4b354 feat(#956): add MemPalace memory capability (ADR-857 feature plug-in) (#1201)
* feat(#956): add MemPalace memory capability (ADR-857 feature plug-in)

Adds an opt-in, default-resilient ADR-857 feature capability that wires
MemPalace (local-first memory: MCP server + CLI) into the GSD loop:
deliberate recall before discuss/plan and verbatim + temporal-KG capture
at phase boundaries. Three memory modes (augment default; kg_backend and
replace forward-declared). Master gate mempalace.enabled (default off);
every hook onError:skip, zero gates; absent/disabled MemPalace => loop
unchanged. Transport is rendered-markdown only — MemPalace runs
out-of-process, no third-party code in gsd-core (ADR-857 §7).

Capability: capabilities/mempalace/ (manifest + 2 fragments), skills
commands/gsd/mempalace-{recall,capture}.md, agent
agents/gsd-mempalace-curator.md. Registration: ns-context router,
utility cluster, KNOWN_SKILLS, help full.md, model-catalog, copilot
install list, size baselines; regenerated capability-registry +
inventory manifest. ship:post wired into ship.md (wire-on-demand).

HELD on #1196: this capability also declares hooks at discuss:pre and
discuss:post, which are structurally un-wireable until the host-loop
conformance model covers the discuss phase (discuss-phase.md is not in
HOST_LOOP_FILES). The phase6-capstone-conformance gate therefore fails
on exactly those two orphaned points by design — see #1196. Once #1196
lands, rebase onto next and the gate goes green with no further change.
