Bump all workspace crates, the node package and pyproject to 2.3.0, finalize
the changelog and add upgrade notes for the behaviour changes.

Eight MemoryConfig fields (float16, compression, compression_level,
compact_threshold, hebbian_boost, decay_factor, wal_enabled, wal_max_entries)
were never written to /meta, so reopening a store silently reset them to
defaults — a compressed store was rewritten uncompressed by the first
checkpoint after a reopen, and wal_enabled=false flipped back to true. They
are now stored as /meta attributes; each is optional on load so older files
keep opening with the previous defaults, and non-finite floats are ignored.
Writing the round-trip test exposed that `compression = true` never worked in
a default build: the embeddings dataset called with_zstd() unconditionally but
the agent crate never enabled the zstd feature, so every checkpoint failed
with "unsupported filter: 32015". The default build now compresses with
deflate (always available, pure Rust path); Zstd is opt-in via a new `zstd`
agent feature.

Bump all workspace crates, the node package and pyproject to 2.2.0 and
finalize the changelog. The repository URL in every manifest pointed at a

Add [workspace.dependencies] to the root Cargo.toml for the four
duplicated-across-many-crates dependencies flagged by the earlier review:
tempfile (7 crates), criterion (6), half (4 — real version skew, clawhdf5-gpu
pinned 2.7 while others used bare 2), and serde (4). Update every consuming
crate to `dep = { workspace = true }`, preserving crate-local `optional =
true` where it already existed. half now resolves uniformly to 2.7.x
workspace-wide instead of two separate semver ranges.
Also fixed clawhdf5-filters/Cargo.toml's stale "rustyhdf5" description
while touching the file (same class of leftover rename as prior fixes).
Not touching rayon/byteorder/clap (no skew found, lower priority).
Bumps [workspace.package] and all 17 crate package versions (and internal
path-dependency requirements) from 2.0.0 to 2.1.0 for a coordinated release.

Resolves two gaps found in a project-state review:
1. Python build was broken: PyO3/numpy 0.23 caps at Python 3.13 but the
environment has 3.14. Bumped to 0.28 and updated the two breaking APIs
(PyObject -> Py<PyAny>, allow_threads -> detach). The extension module now
imports and round-trips under Python 3.14, unblocking cargo build --workspace.
2. The "HNSW vector search over agent memories" headline was unwired:
clawhdf5-ann had zero dependents and the agent used a linear cosine+BM25 scan.
- clawhdf5-ann is now a live index: insert, mark_deleted (soft delete with a
deleted bitset, traversed but never returned), compact, and a format
version tag (v2) with backward-compatible load of v1 files.
- clawhdf5-agent wires HNSW behind the `hnsw` feature (ON by default). The
index mirrors the cache (node id == cache index) and self-heals: it rebuilds
whenever hnsw_synced_len drifts from cache.len(), so unhooked pushes can't
desync it. Non-indexable stores (no/zero-dim/mixed embeddings) and queries
whose dim doesn't match fall back to the exact linear scan.
- hybrid.rs gains merge_vector_keyword, shared by the linear and HNSW paths.
- tests/hnsw_integration.rs validates recall vs a brute-force oracle plus
insert/delete/batch behaviour.
Disable HNSW for exact search with `--no-default-features --features float16`.
