release: v0.7.2 (#301)

Patch release over v0.7.1: write-path latency reductions (#288 direct table
opener, #298 schema-once + open-each-table-once) and three correctness fixes on
the maintenance and recovery paths (#297 optimize survives a cross-process write
race, #291 optimize compacts the internal metadata tables + non-destructive
auto_cleanup strip, #296 recovery converges under a concurrent manifest advance).
No breaking changes, no on-disk format change, no migration.

Version coherence: all 7 crate manifests + path-dep constraints, Cargo.lock,
openapi.json, and the AGENTS.md surveyed version bumped 0.7.1 -> 0.7.2. Build
green under --locked; OpenAPI drift check green.

+# Omnigraph v0.7.2
+
+A patch release over v0.7.1: write-path latency reductions plus three
+correctness fixes on the maintenance and recovery paths. No breaking changes, no
+on-disk format change, and no migration — drop-in over v0.7.1.
+
+## Performance
+
+- **Write opens go direct, schema validates once (#288, #298).** Write opens
+  used to route through the per-table Lance namespace catalog, which re-opened
+  the dataset just to read its location and re-resolved the latest version on
+  every table open — an O(commit-depth) double resolution that dominated write
+  latency on object stores (~70%). Writes now open each touched data table
+  directly by its manifest-recorded location (Lance's O(1) version-hint path),
+  validate the schema contract once per write instead of ~4×, and open each
+  touched table once instead of 4×.
+
+- **`optimize` compacts the internal metadata tables (#291).** `optimize`
+  previously iterated only node/edge tables, so the internal `__manifest`,
+  `_graph_commits`, and `_graph_commit_actors` tables accumulated one fragment
+  per commit and were never compacted — making every write's metadata scan grow
+  with commit history. `optimize` now compacts all three, so a periodically
+  optimized long-lived graph keeps its per-write metadata scan flat in history.
+
+## Fixes
+
+- **`optimize` survives a cross-process write race (#297).** A CLI `optimize`
+  racing a served write on the same table could fail: the in-process write queue
+  doesn't serialize across processes, so a concurrent insert/delete advancing the
+  manifest between optimize's compaction and its publish broke the strict
+  equality CAS. Optimize now reopens-and-replans on a genuine Lance conflict and
+  fast-forwards its publish monotonically, so a maintenance compaction never
+  fails a live write. Bounded retry; sustained contention surfaces a loud
+  conflict rather than dropping work.
+
+- **`optimize` is non-destructive on upgraded graphs (#291).** A graph created by
+  a pre-0.7.0 binary carries an on-by-default Lance auto-cleanup config; under it,
+  optimize's compaction commit could fire Lance's version-GC hook and prune
+  `__manifest`-pinned versions (breaking snapshots and time travel). Optimize now
+  strips any stale `lance.auto_cleanup.*` config off every table — data and
+  internal — before its HEAD-advancing commits, so compaction can never GC pinned
+  versions.
+
+- **Recovery converges instead of failing `open` under a concurrent manifest
+  advance (#296).** The open-time recovery sweep published its roll-forward at the
+  sidecar's pinned expected version; if another writer advanced the manifest
+  during the classify→publish window, the CAS failed and aborted the whole
+  `Omnigraph::open`. The sweep now treats roll-forward as "the manifest reflects
+  the sidecar's committed state," not "this sweep won the CAS": on a CAS loss it
+  re-reads the live manifest and, when the sidecar's intent is already satisfied,
+  records the recovery and deletes the sidecar idempotently — so a concurrent
+  advance no longer fails the open. (The destructive roll-back twin still defers
+  to a cross-process lease, as documented.)
+
+## Upgrade notes
+
+Drop-in over v0.7.1 — no configuration, schema, or data changes. Upgrade the
+server and CLI together as usual. Graphs created on v0.7.1 read and write
+identically on v0.7.2; the optimize non-destructive fix additionally protects
+graphs created by pre-0.7.0 binaries from version GC during compaction.
