Complete InterruptSession implementation and enable resume during running status (#230)

* Complete InterruptSession implementation - Fix syscall import compilation error in claudecode-go - Add proper race condition handling in session manager - Move InterruptSessionRequest to types.go for consistency - Add InterruptSessionResponse with success/status fields - Add 'completing' status for graceful shutdown semantics - Update event publishing to use completing status - Add TypeScript types for interrupt operations - Update Rust client with proper response handling - Fix unit tests for new completing status - All 109 tests passing with full type safety * git ignore test-results.json * Enable resume during running status - Allow continueSession to accept running sessions in addition to completed - Interrupt running sessions before resuming to ensure clean state transitions - Reorder validation to check claude_session_id before attempting interrupt - Provide clear error messages for orphaned sessions (running but no claude_session_id) - Add comprehensive unit and integration tests for new resume-during-running functionality - Maintain backward compatibility for existing completed session resume workflow * fix: force bash shell in CI to prevent shell compatibility errors The CI was using /bin/sh which doesn't support bash-specific syntax like [[ ]] used in hack/run_silent.sh lines 73 and 88. This caused '/bin/sh: [[: not found' errors that made tests appear to pass when they may not have actually run properly. * add fail-fast shell syntax validation to prevent silent CI failures - Added 'set -e' to hack/run_silent.sh to exit on any command failure - Added 'bash -n' syntax validation before sourcing shell scripts in Makefile - This ensures CI will fail immediately if shell scripts have syntax errors - Prevents scenarios where malformed scripts cause tests to appear to pass when they may not have actually executed properly * fix: resolve Claude Code streaming JSON schema compatibility issues - Fix pointer-to-loop-variable bug in streaming test event collection - Add missing system event fields (CWD, Model, PermissionMode, APIKeySource) - Update Usage struct to match current Claude Code schema (ServerToolUse, ServiceTier) - Fix cost field mapping from TotalCost to CostUSD throughout codebase - Improve message event validation to handle user vs assistant differences - All schema compatibility tests now pass * fix: complete TotalCost to CostUSD field migration across codebase - Remove deprecated TotalCost field assignments in session manager - Update TUI to display CostUSD instead of TotalCost - Remove TotalCost test assertions in result population tests - Completes schema consistency with Claude Code SDK changes * fix: make shell scripts POSIX-compliant to prevent CI failures - Replace bash-specific [[ with POSIX [ syntax in run_silent.sh - Replace == with = for POSIX compatibility - Simplify test-ts to use run_silent instead of complex JSON parsing - Remove SHELL := /bin/bash from all Makefiles (no longer needed) - Remove shell: bash from GitHub Actions (no longer needed) - Keep set -e for fail-fast behavior and syntax validation - Scripts now work consistently in both bash and sh environments * fix: use sh -n instead of bash -n for syntax validation Since scripts are now POSIX-compliant, use sh for syntax validation to match the target shell environment and ensure consistency.
