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

* Fix missing before_tool_call hook integration
- Add hook call in handleToolExecutionStart before tool execution begins
- Support parameter modification via hookResult.params
- Support tool call blocking via hookResult.block with custom blockReason
- Fix try/catch logic to properly re-throw blocking errors using __isHookBlocking flag
- Maintain tool event consistency by emitting start/end events when blocked
- Addresses GitHub issue #6535 (1 of 8 unimplemented hooks now working)

* Add comprehensive test suite for before_tool_call hook
- 9 tests covering all hook scenarios: no hooks, parameter passing, modification, blocking, error handling
- Tests tool name normalization and different argument types
- Verifies proper error re-throwing and logging behavior
- Maintained in fork for regression testing
* Fix all issues identified by Greptile code review
Address P0/P1/P3 bugs:
P0 - Fix parameter mutation crash for non-object args:
- Normalize args to objects before passing to hooks (maintains hook contract)
- Handle parameter merging safely for both object and non-object args
P1 - Add missing internal state updates when blocking tools:
- Set toolMetaById metadata like normal flow
- Call onAgentEvent callback to maintain consistency
- Emit events in same order as normal tool execution
P1 - Fix test expectations to match implementation reality:
- Non-object args normalized to {} for hook params (not passed as-is)
- Add test for safe parameter modification with various arg types
- Update mocks to verify state updates when blocking
P3 - Replace magic __isHookBlocking property with dedicated ToolBlockedError class:
- More robust error handling without property collision risk
- Cleaner control flow that's serialization-safe

* security(web): sanitize WhatsApp accountId to prevent path traversal
Apply normalizeAccountId() from routing/session-key to
resolveDefaultAuthDir() so that malicious config values like
"../../../etc" cannot escape the intended auth directory.
Fixes#2692
* fix(web): check sanitized segment instead of full path in Windows test
* style(web): fix oxfmt formatting in accounts test
