* Fix subagent announce race and timeout handling
Bug 1: Subagent announce fires before model failover retries finish
- Problem: CLI provider emitted lifecycle error on each attempt, causing
subagent registry to prematurely call beginSubagentCleanup() and announce
with incorrect status before failover retries completed
- Fix: Removed lifecycle error emission from CLI provider's attempt-level
.catch() in agent-runner-execution.ts. Errors still propagate to
runWithModelFallback for retry, but no intermediate lifecycle events
are emitted. Only the final outcome (after all retries) emits lifecycle
events.
Bug 2: Hard 600s per-prompt timeout ignores runTimeoutSeconds=0
- Problem: When runTimeoutSeconds=0 (meaning 'no timeout'), the code
returned the default 600s timeout instead of respecting the 0 setting
- Fix: Modified resolveAgentTimeoutMs() to treat 0 as 'no timeout' and
return a very large timeout value (30 days) instead of the default.
This avoids setTimeout issues with Infinity while effectively providing
unlimited time for long-running tasks.
* fix: emit lifecycle:error for CLI failures (#6621) (thanks @tyler6204)
* chore: satisfy format/lint gates (#6621) (thanks @tyler6204)
* fix: restore build after upstream type changes (#6621) (thanks @tyler6204)
* test: fix createSystemPromptOverride tests to match new return type (#6621) (thanks @tyler6204)
* feat: Implement paragraph boundary flushing in block streaming
- Added `flushOnParagraph` option to `BlockReplyChunking` for immediate flushing on paragraph breaks.
- Updated `EmbeddedBlockChunker` to handle paragraph boundaries during chunking.
- Enhanced `createBlockReplyCoalescer` to support flushing on enqueue.
- Added tests to verify behavior of flushing with and without `flushOnEnqueue` set.
- Updated relevant types and interfaces to include `flushOnParagraph` and `flushOnEnqueue` options.
* fix: Improve streaming behavior and enhance block chunking logic
- Resolved issue with stuck typing indicator after streamed BlueBubbles replies.
- Refactored `EmbeddedBlockChunker` to streamline fence-split handling and ensure maxChars fallback for newline chunking.
- Added tests to validate new chunking behavior, including handling of paragraph breaks and fence scenarios.
- Updated changelog to reflect these changes.
* test: Add test for clamping long paragraphs in EmbeddedBlockChunker
- Introduced a new test case to verify that long paragraphs are correctly clamped to maxChars when flushOnParagraph is enabled.
- Updated logic in EmbeddedBlockChunker to handle cases where the next paragraph break exceeds maxChars, ensuring proper chunking behavior.
* refactor: streamline logging and improve error handling in message processing
- Removed verbose logging statements from the `processMessage` function to reduce clutter.
- Enhanced error handling by using `runtime.error` for typing restart failures.
- Updated the `applySystemPromptOverrideToSession` function to accept a string directly instead of a function, simplifying the prompt application process.
- Adjusted the `runEmbeddedAttempt` function to directly use the system prompt override without invoking it as a function.

Add AbortSignal.timeout() to both fetch calls in download.ts to prevent
indefinite hangs when Telegram API is slow or unresponsive.
- getTelegramFile(): 30s timeout for metadata API call
- downloadTelegramFile(): 60s timeout for file download
Both functions now accept optional timeoutMs parameter for configurability.
Fixes#6849

- Update @mariozechner/pi-agent-core, pi-ai, pi-coding-agent, pi-tui to 0.51.0
- Delete src/types/pi-coding-agent.d.ts (declared additionalExtensionPaths which SDK never supported)
- Fix ToolDefinition.execute signature (parameter order changed in 0.51.0)
- Remove dead additionalExtensionPaths from createAgentSession calls
Add timeout protection to prevent indefinite hangs when Urbit server
becomes unresponsive or network partition occurs.
Changes:
- Add AbortSignal.timeout(30_000) to 7 one-shot fetch calls
- Add AbortController with 60s connection timeout to SSE stream fetch
(clears timeout after headers received to avoid aborting active stream)
Affected methods: sendSubscription, connect, openStream, poke, scry, close
Fixes#5266
