* fix(plugins): expose ephemeral sessionId in tool contexts for per-conversation isolation
The plugin tool context (`OpenClawPluginToolContext`) and tool hook
context (`PluginHookToolContext`) only provided `sessionKey`, which
is a durable channel identifier that survives /new and /reset.
Plugins like mem0 that need per-conversation isolation (e.g. mapping
Mem0 `run_id`) had no way to distinguish between conversations,
causing session-scoped memories to persist unbounded across resets.
Add `sessionId` (ephemeral UUID regenerated on /new and /reset) to:
- `OpenClawPluginToolContext` (factory context for plugin tools)
- `PluginHookToolContext` (before_tool_call / after_tool_call hooks)
- Internal `HookContext` for tool call wrappers
Thread the value from the run attempt through createOpenClawCodingTools
→ createOpenClawTools → resolvePluginTools and through the tool hook
wrapper.
Closes#31253
Made-with: Cursor
* fix(agents): propagate embedded sessionId through tool hook context
* test(hooks): cover sessionId in embedded tool hook contexts
* docs(changelog): add sessionId hook context follow-up note
* test(hooks): avoid toolCallId collision in after_tool_call e2e
