fix(memory-lancedb): prevent cross-agent memory leakage (#103799)

* fix(memory-lancedb): gate auto-recall and auto-capture on per-agent memorySearch.enabled (#103590)

The before_prompt_build auto-recall hook only checked the plugin-level
autoRecall flag, so agents configured with memorySearch.enabled: false
still received <relevant-memories> injected from the shared LanceDB store
- leaking one agent's private memories into another agent's prompts. Gate
both recall injection and agent_end auto-capture on the current agent's
memorySearch.enabled (per-agent entry wins over agents.defaults; unset
means enabled), mirroring core resolveMemorySearchConfig semantics.

* fix(memory-lancedb): normalize agent ids before the memorySearch gate

Review follow-up on #103799: a configured id like 'XiaoHuo' or one with
surrounding whitespace missed the exact-match per-agent override and
inherited the enabled default, leaving the disclosure path active.
Normalize both the hook agent id and configured entry ids with the SDK
normalizeAgentId before comparing.

+Every memory is owned by one agent. Recall, duplicate detection, capture,
+listing, raw queries, and deletion all enforce that owner before returning or
+mutating rows. An agent with `memorySearch.enabled: false` (in `agents.list[]`
+or via `agents.defaults`) also gets none of the `memory_recall`, `memory_store`,
+or `memory_forget` tools and does not participate in automatic recall or
+capture, even when the plugin-level `autoRecall`/`autoCapture` flags are on.

 ## Commands
 
 `memory-lancedb` registers the `ltm` CLI namespace whenever it is installed
 (not only when it owns the active memory slot):
 
 ```bash
-openclaw ltm list [--limit <n>] [--order-by-created-at]
-openclaw ltm search <query> [--limit <n>]
-openclaw ltm stats
+openclaw ltm list [--agent <id>] [--limit <n>] [--order-by-created-at]
+openclaw ltm search <query> [--agent <id>] [--limit <n>]
+openclaw ltm stats [--agent <id>]
 ```
 
 `ltm query` runs a non-vector query directly against the LanceDB table:
 
 ```bash
-openclaw ltm query --cols id,text,createdAt --limit 20
+openclaw ltm query --agent research --cols id,text,createdAt --limit 20
 openclaw ltm query --filter "category = 'preference'" --order-by createdAt:desc

 ```
 
+The plugin keeps one LanceDB table and stores a normalized agent owner on each
+row. This is a storage boundary, not a post-search filter: agent ownership is
+applied before vector ranking and is included in list, query, count, and delete
+predicates. `ltm query --filter` accepts one validated comparison over the
+public output columns. The store builds that comparison separately from the
+mandatory owner predicate, so a filter cannot widen the query to another
+agent.
+
+Databases created before per-agent ownership have no reliable row provenance.
+On upgrade, `openclaw doctor --fix` assigns those legacy rows once to the
+configured default agent. Runtime access fails closed until that migration has
+completed; other agents never inherit the old shared rows.
+
 `storageOptions` accepts string key/value pairs for LanceDB storage backends
 (e.g. S3-compatible object storage) and supports `${ENV_VAR}` expansion:
