fix(agents): preserve messaging dedupe thread ids

CHANGELOG.md

@@ -49,6 +49,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/logging: expand leading `~` in `logging.file` before creating the file logger, preventing startup crash loops for home-relative log paths. Fixes #73587.
 - Channels/CLI: keep `openclaw channels list --json` usable when provider usage fetching fails, and report per-provider usage errors without aborting the channel list. Refs #67595.
 - Agents/messaging: deliver distinct final commentary after same-target `message` tool sends while still deduping text/media already sent by the tool, so short closing remarks are no longer silently dropped. Fixes #76915. Thanks @hclsys.
+- Agents/messaging: preserve string thread IDs when matching message-tool reply dedupe routes, avoiding precision loss on numeric-looking topic IDs before channel plugin comparison. Thanks @vincentkoc.
 - OpenAI Codex: let SSRF-guarded provider requests inherit OpenClaw's undici IPv4/IPv6 fallback policy, so ChatGPT-backed Codex runs recover on IPv4-working hosts when DNS still returns unreachable IPv6 addresses. Fixes #76857. Thanks @jplavoiemtl and @SymbolStar.
 - Gateway/systemd: preserve operator-added secrets in the Gateway env file across re-stage while clearing OpenClaw-managed keys (such as `OPENCLAW_GATEWAY_TOKEN`) so a fresh staging value is never shadowed by a stale env-file copy; operator secrets are also retained when the state-dir `.env` is empty. Fixes #76860. Thanks @hclsys.
 - Plugin updates: do not short-circuit trusted official npm updates as unchanged when the default/latest spec still resolves to an already-installed prerelease that the installer should replace with a stable fallback. Thanks @vincentkoc.
