feat(8.0): API simplification — remove neural()/Db.search, one storage path key, integration→0

8.0 RC cleanup toward "one place per thing, zero-config, no deprecation":

- Remove the `brain.neural()` clustering namespace (ImprovedNeuralAPI + the dead
  legacy NeuralAPI + the neural CLI + neural-only types). Similarity is `find({vector})`
  / `similar({to})`; attribute grouping is the aggregation `GROUP BY` engine. The separate
  entity-extraction / smart-import feature (NeuralImport, NeuralEntityExtractor, SmartExtractor,
  NaturalLanguageProcessor, `brain.extract()`/`brain.nlp()`) is kept.
- Remove `Db.search()`; `find()` is the one query verb (accepts a bare string or FindParams).
  Fix the bundled MCP client, which called a non-existent `brain.search(query, limit)` →
  now `find({ query, limit })`.
- Storage config: collapse to one canonical top-level `path` key. The pre-8.0 aliases
  (`rootDirectory`, `options.*`, `fileSystemStorage.*`) are removed and now THROW with the
  exact rename instead of silently defaulting to `./brainy-data` on upgrade. A single resolver
  feeds createStorage, the 7.x→8.0 migration probe, and the plugin-factory handoff, so a native
  storage provider resolves the identical root (no split-brain).
- Fix `similar({ threshold })`: the min-similarity filter was silently dropped; it is now
  applied as a post-filter on `result.score` (the documented way to bound semantic results).
- Fix `vfs.rename()` on a directory: child path updates spread the entity vector into `update()`
  and failed dimension validation; they are metadata-only updates now.
- Fix `vfs.move()`: copy+delete orphaned the content-addressed content blob (the destination
  shared the source hash, then unlink removed it). `move()` now delegates to `rename()` — an
  in-place path change that preserves the blob and the entity id, for files and directories.
- Fix streaming import: the bulk fast path never flushed mid-import nor signalled queryability.
  Entity writes are now chunked by a progressive flush interval (100 → 1000 → 5000); each chunk
  flushes and emits `progress.queryable`, so imported data is queryable during the import.
- Sweep all docs, comments, and JSDoc for the removed/changed APIs.

Integration suite: 49 files / 588 passed / 0 failed. Unit: 80 files / 1456 passed, no type errors.

/**
* @module tests/unit/storage/storage-path-resolution
* @description Acceptance suite for the consolidated filesystem storage-path
* surface (8.0). Brainy resolves the on-disk root through ONE function,
* {@link resolveFilesystemRoot}. 8.0 is a clean break: `path` is the ONE
* supported key (the rest of the API already speaks it: `persist(path)`,
* `Brainy.load(path)`, `asOf(path)`, `restore(path)`). The pre-8.0 aliases
* (`rootDirectory`, `options.*`, `fileSystemStorage.*`) were REMOVED and now
* THROW with the rename never a silent default that would misplace data.
* Three things must hold and are pinned here:
* 1. CLEAN BREAK `path` resolves; any removed alias throws.
* 2. TYPE INFERENCE a bare `path` (no `type`) implies filesystem.
* 3. COR-SAFETY a plugin storage factory receives the RESOLVED `path`, so a
* native side (mmap / getBinaryBlobPath) can never split-brain onto a
* different directory than the one brainy itself uses.
