fix(ollama): preserve streaming usage compat

CHANGELOG.md

@@ -19,6 +19,7 @@ Docs: https://docs.openclaw.ai
 - CLI/models: keep route-first `models status --json` stdout reserved for the JSON payload by routing auth-profile and startup diagnostics to stderr. Fixes #72962. Thanks @vishutdhar.
 - Sessions: ignore future-dated session activity timestamps during reset freshness checks and cap future `updatedAt` values at the merge boundary so clock-skewed messages cannot keep stale sessions alive forever. Fixes #72989. Thanks @martingarramon.
 - Plugins/CLI: allow managed plugin installs when the active extensions root is a symlink to a real state directory, while keeping nested target symlinks blocked and suppressing misleading hook-pack fallback errors for install-boundary failures. Fixes #72946. Thanks @mayank6136.
+- Providers/Ollama: mark discovered Ollama catalog models as supporting streaming usage metadata so token accounting stays enabled for local models. (#72976) Thanks @sdeyang.
 - Gateway/startup: keep hot Gateway boot paths on leaf config imports and add max-RSS reporting to the gateway startup bench so low-memory startup regressions are visible before release. Thanks @vincentkoc.
 - WebChat: read `chat.history` from active transcript branches, drop stale streamed assistant tails once final history catches up, and coalesce duplicate in-flight Control UI submits, so rewritten prompts, completed replies, and rapid send events no longer render or process twice. Fixes #72975, #72963, and #72974. Thanks @dmagdici, @lhtpluto, and @Benjamin5281999.
 - WebChat/TTS: persist automatic final-mode TTS audio as a supplemental audio-only transcript update instead of adding a second assistant message with the same visible text. Fixes #72830. Thanks @lhtpluto.
