chopratejas e4e28b65f4 fix(proxy): surface CompressionDecision.passthrough_reason in tags ... Adds ``CompressionDecision.apply_to_tags(tags)`` — a one-liner mutator that stamps the passthrough reason into a tags dict for downstream observability. Each migrated handler now calls ``_decision.apply_to_tags(tags)`` immediately after ``CompressionDecision.decide(...)``. The tags dict flows unchanged into every downstream ``RequestOutcome(tags=tags, ...)`` construction, which the funnel surfaces in ``RequestLog.tags`` — same mechanism the funnel already uses for ``client``. Dashboards can now slice passthrough traffic by cause: * tags["passthrough_reason"] == "bypass_header" * tags["passthrough_reason"] == "compression_disabled" * tags["passthrough_reason"] == "no_messages" * tags["passthrough_reason"] == "license_denied" No-op when ``should_compress=True`` — compressing requests don't carry the tag, so absence vs presence is itself the signal. Bonus fix: ``handle_gemini_count_tokens`` was the one Gemini handler that never pulled tags out of headers, so its emitted ``RequestOutcome`` reached the dashboard without any of the per- request slicing keys. Added the missing ``tags = self._extract_tags (request.headers)`` and threaded ``tags=tags`` into its outcome. Closes the observability loop opened by PR #477: the four Gemini- bypass-bug fixes are now visible in the request-log feed the moment they fire.		2026-05-15 14:40:00 -07:00
