### BREAKING CHANGES

* total_timeout_ms is renamed to batch_total_timeout_ms. Config files using the old name must be updated. No default value change.

Docs updated (reference + perf-tuning guide) with a short explainer on the per-attempt vs total deadline distinction. Two new unit tests pin the policy wiring: socket_timeout_ms propagates to all three scopes, and is omitted (not injected as None) when unset.

* refactor(aerospike): use MAP_KEY_ORDERED, KEY_DIGEST, and instance-scoped client

Cheap-win cleanups flagged in review, all touching the same small patch of write-path and lifecycle code.

* Map CDTs are now created with MAP_KEY_ORDERED. map_get_by_key / map_remove_by_key on an ordered map are O(log N) in the map size instead of O(N); matters on reads of wide feature views and on the update() background scan (which walks every record in the project's set).

* Writes drop POLICY_KEY_SEND and rely on the client default (POLICY_KEY_DIGEST). The serialized entity key is no longer stored alongside each record, saving per-record storage the read path never consumes (batch_operate preserves request order; results are paired back by zip in online_read).

* _client moves from a class attribute to an instance attribute (set in __init__). Previously two AerospikeOnlineStore instances could share the cached client through class state until one wrote self._client. With the instance attribute the state is always per-instance from construction.

* Drop MongoDB references from class docstrings and comments (they referred to how the storage layout was derived rather than documenting current behavior). Also rewrite the _build_batch_writes docstring to describe the policies applied on the write path.

Unit test assertions for the write-path record are updated: bw.policy is now None (client default applies) and map ops carry map_policy={'map_order': MAP_KEY_ORDERED}. All three docker-backed integration tests still pass end-to-end (cross-FV upsert, update() background scan, full feature-store round-trip), so the read/write shape survives the ordering and policy changes against a real server.

* feat(aerospike): add per-FV namespace/set overrides and prewriting hook

Adds three configuration knobs to AerospikeOnlineStoreConfig:

- namespace_overrides: pin individual feature views to a different
  Aerospike namespace (e.g. RAM-only vs. SSD-backed) without splitting
  the project across stores.
- set_overrides: place a feature view in its own set so admin ops on
  it (truncate, scan-based deletes during `feast apply`) do not touch
  records of other views.
- prewriting_hook: import-string-resolved callable invoked once per
  online_write_batch with the rows about to be written, returning the
  rows that actually go on the wire. Resolved and cached on first use;
  returning [] short-circuits the wire call.

Read, write, update and teardown paths all honour the per-FV ns/set
resolution. update() groups dropped feature views by their resolved
(ns, set) pair and issues one background scan per group. teardown()
truncates every unique (ns, set) pair the project may have written to,
including the store-level default.

Adds 22 unit tests for the new behaviour and updates 3 existing call
sites of _build_batch_writes for the new namespace= parameter. Adds a
sample hook module under examples/online_store/aerospike_overrides_and_hooks/
and corresponding sections in docs/reference/online-stores/aerospike.md.

- Treat empty projected feature maps as present FV slots (is not None)
- Return {} from _normalize_projected_features([]) instead of None
- Fix projection unit test mock/assertions
- Correct prewriting_hook config docstring
