feat(cli): Wire --full flag for embed, add sync stage spinners

- Add --full / --no-full flag pair to EmbedArgs with overrides_with
  semantics matching the existing flag pattern. When active, atomically
  DELETEs all embedding_metadata and embeddings before re-embedding.

- Thread the full flag through run_embed -> run_sync so that
  'lore sync --full' triggers a complete re-embed alongside the full
  re-ingest it already performed.

- Add indicatif spinners to sync stages with dynamic stage numbering
  that adjusts when --no-docs or --no-embed skip stages. Spinners are
  hidden in robot mode.

- Update robot-docs manifest to advertise the new --full flag on the
  embed command.

- Replace hardcoded schema version 9 in health check with the
  LATEST_SCHEMA_VERSION constant from db.rs.
