docs(openclaw-plugin): drop agent_end from README hook list per #1866

[r266-tech]

Summary

#1866 (Mijamind719→ qin-ctx, merged 2026-05-06T08:50Z) explicitly removed the agent_end hook from examples/openclaw-plugin/index.ts because OpenClaw 5.2 blocks that typed hook for non-bundled plugins without conversation access (per the PR description: "the agent_end hook is removed because 5.2 blocks that typed hook for non-bundled plugins without conversation access; session routing is already recorded through session_start/session_end.").

After the merge, examples/openclaw-plugin/index.ts only registers session_start, session_end, and before_reset (verified with grep -n "api.on(" examples/openclaw-plugin/index.ts):

api.on("session_start", async (_event, ctx) => { ... });
api.on("session_end",   async (_event, ctx) => { ... });
api.on("before_reset",  async (_event, ctx) => { ... });

But the hook-layer bullet in README.md (line 22) and README_CN.md (line 22) still list agent_end. Drop it so the README matches the runtime registration.

Scope

• examples/openclaw-plugin/README.md — removed , + `agent_end` from the hook-layer bullet
• examples/openclaw-plugin/README_CN.md — removed `agent_end`、 from the same bullet (Chinese)

Pure docs, no code or behavior change. Refs #1866.
