- 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
* 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
