v0.3.1

[0.3.1] - 2026-05-15

Added

• palace_import MCP tool — import drawers from a JSON snapshot produced
  by palace_export. Skips drawers that already exist (idempotent). Returns
  inserted, skipped, and total counts.
• palace_upgrade_embeddings MCP tool — re-embeds all drawers using the
  current embedding model. Run after upgrading the model to keep search quality
  consistent.
• palace_prune MCP tool — deletes drawers filed more than older_than_days
  days ago. Irreversible; export first if unsure.
• palace prune --older-than-days N [--dry-run] CLI command.
• palace upgrade-embeddings CLI command.
• palace timeline [--entity <name>] CLI command — human-readable
  chronological view of knowledge-graph facts, optionally filtered to one entity.
