v1.12.0

Added

• Per-folder memory is now first-class: the deployed agent skill explains that runtime and data root (MEMORIA_HOME) are separate, so any clean folder can get its own memory by running setup there. Deployed SKILL.md adds self-location of the data root, a fail-closed "check before write" flow, and a new-folder setup walkthrough.
• resolveMemoriaHomeInfo() reports how MEMORIA_HOME was resolved (env / detected / fallback). getMemoriaHome() delegates to it with unchanged behavior and return type.

Changed

• doctor no longer reports MEMORIA_HOME as always healthy. When the home was resolved by silent fallback (folder never set up, no env), the check now fails with an actionable fix hint, and doctor --json exposes a homeSource field.
• The deployed agent skill now installs to <memoria-home>/.agents/skills/memoria/ (was <memoria-home>/.agents/memoria-memory-sync/) and is named memoria, so agents discover it as the memoria skill in active_skills. The repo-side source directory skills/memoria-memory-sync/ is unchanged.
• README / README.zh-TW / docs/INSTALL.md updated for the new deployed path, skill name, and per-folder memory model.
