clawhdf5-migrate wrote a layout of its own (/chunks, /sessions,
/entities, /relations, root attributes, no /meta or schema_version) that
HDF5Memory::open rejects, so a "migrated" SQLite database could not be
used as agent memory — contrary to the README.
It now writes through the agent's own API (HDF5Memory::create/open,
save_batch, the session cache and the knowledge graph), so there is no
second copy of the schema:
- sessions and entities/relations carry over; deleted rows become
deleted records (or are left out with --skip-deleted);
- embeddings follow the library default (float16), --f32 opts out and
--float16 is a hidden no-op, as in clawhdf5-cli; the `half`-based
conversion is gone;
- every source row is checked before the output is created: a wrong
embedding length, an empty embedding, a dimension that differs from
an existing store's, or a float16 value beyond +-65504 is an error
naming the chunk id, and an existing store is left untouched;
- --incremental opens the existing store, adds only rows it does not
hold (matched by content) and follows the source's deleted flags;
- a source with no memory rows needs --embedding-dim;
- validation reads the result back with HDF5Memory::open_read_only,
compares every field (embeddings bit for bit, round_to_f16 of the
source for float16) and checks a migrated record is found by search.
clawhdf5-agent gains HDF5Memory::sessions()/sessions_mut(),
HDF5Memory::delete_batch (one save, all-or-nothing, no auto-compact),
SessionCache::add_at, and re-exports SessionCache/SessionEntry.
The old layout's per-dataset SHA-256 provenance attributes have no place
in the agent schema and are gone. An adversarial review found two
blockers (silent truncation of long embeddings; an --incremental
dimension check that could never fire) and four majors (a failed run
wiping the existing store, dim-0 stores, deleted-flag drift); all are
fixed with regression tests. 42 migrate tests, incl. h5py opening a
migrated store.

Sweep of the docs after the v2.0.0 rename and recent changes:
- Per-crate READMEs (13 files): rename leftover rustyhdf5-*/edgehdf5-*
package names and badges to clawhdf5-*, bump usage versions to 2.1.0.
- README: update stale test badge (417 -> 1500+), workspace stats
(15 crates/72K -> 17 crates/84K), agent crate stats (20.7K/32 modules),
and add the missing clawhdf5-napi and clawhdf5-bench crates to the tree.
- CLAUDE.md: correct the CLI subcommand list (inspect/dump/index/search ->
the actual create/save/search/recall/stats/flush-wal/agents-md/export/snapshot).
No code changes. Verified there are zero todo!()/unimplemented!() macros and
no TODO/FIXME comments in the tree.
