0.58.3: Typing Cancellation Diagnostics

• Typing diagnostics: Ended typing loops no longer log cancellation-only authority refusals as API failures. Real HTTP/network failures retain their provenance and diagnostics even if authority expires before settlement. Requests remain rejected and single-attempt; callbacks stay local. Native late-success/failure and follower-ACK regressions cover this case, not the cause of the live report.
• Prompt-cache acceptance: Reporter-provided live Anthropic captures and connected-session measurements confirm the released fix across tool changes, resume, local/Telegram switches and reconnect, with no new thinking drops in the tested runs. The remaining live-confirmation gate is closed; connected wire capture and broader model/cache-expiry coverage remain outside this evidence. Already-lost thinking is not reconstructed.
