Giant pass: storage API docs, trust/consensus/routing code, category guides

Complete manual documentation cleanup for the storage stack and expand
category-level guides across the library.

Documentation (23 storage modules):
- Rewrite Methods sections in all storage-hypercore, storage-hyperbee,
  storage-autobase, and storage-hyperdrive api.md files from index.js
- Remove every "module-specific (see implementation)" placeholder in storage
- Fix bitfield-scheduler, bee-batch-write, bee-range-watch, drive-gc-sweep APIs

Category READMEs (modules/):
- trust-security, consensus-coordination, routing-advanced — tables + hub links
- MODULE_CATEGORIES.md typo fix (scaffold tier description)

Code:
- hyper-p2p-trust-graph: hasEdge(), nodeCount(), getStats with protocol
- hyper-p2p-circuit-breaker: listCircuitIds(), reset()
- hyper-p2p-distributed-lock: getStats merges metrics + active lock counts

Parent workspace (not in this repo) also received doc hubs for all 29
categories in docs/README.md and MODULE_DOC_PASS.md giant-pass tracker.

 ## Methods
 
-### `attach(…)`
+### `attach(bee) → this`
 
-- **Returns:** module-specific (see implementation)
+Validates bee via `assertBee`.
 
-- **Throws:** — (none in method body)
+### `followSince(version = 0) → number`
 
-### `followSince(…)`
+Resets `_cursor` and emits `follow`.
 
-- **Returns:** module-specific (see implementation)
+- **Returns:** new cursor version
+- **Throws:** `version must be non-negative`
 
-- **Throws:**
-  - `Error: version must be non-negative`
+### `recordDiff(entry) → boolean`
 
-### `recordDiff(…)`
+Buffers entries with `version > _cursor`, sorted ascending.
 
-- **Returns:** module-specific (see implementation)
+- **Returns:** `true` when buffered, `false` when version is stale
+- **Throws:** `entry with version required`
 
-- **Throws:**
-  - `Error: entry with version required`
+### `pullDiff(max = 100) → entry[]`
 
-### `pullDiff(…)`
+Drains buffered entries ahead of the cursor up to `max`.
 
-- **Returns:** module-specific (see implementation)
+- **Throws:** `max must be non-negative`
 
-- **Throws:**
-  - `Error: max must be non-negative`
+### `applyDiff(entry) → boolean`
 
-### `applyDiff(…)`
+Advances cursor when `entry.version >= _cursor`; emits `applied`.
 
-- **Returns:** module-specific (see implementation)
+- **Returns:** `false` when entry is older than cursor
+- **Throws:** `entry with version required`
 
-- **Throws:**
-  - `Error: entry with version required`
+### `diffCursor() → number`
 
-### `diffCursor(…)`
+- **Returns:** current version cursor
 
-- **Returns:** module-specific (see implementation)
+### `applyBatch(entries) → number`
 
-- **Throws:** — (none in method body)
+Calls `applyDiff` for each array element.
 
-### `getStats(…)`
+- **Returns:** count of entries applied
+- **Throws:** `entries must be an array`
 
-- **Returns:** module-specific (see implementation)
+### `clearBuffer() → number`
 
-- **Throws:** — (none in method body)
+- **Returns:** number of buffered entries discarded
 
-### `ready(…)`
+### `getStats() → object`
 
-- **Returns:** module-specific (see implementation)
+`{ follows, pulled, applied, cursor, buffered, protocol }`.
 
-- **Throws:** — (none in method body)
+### `async ready() → this`
 
-### `close(…)`
+No-op resolve (library-only).
 
-- **Returns:** module-specific (see implementation)
+### `async close() → void`
 
-- **Throws:** — (none in method body)
+Clears buffer; emits `closed`.
