The file editing tools (file_edit_replace_string, file_edit_insert, file_read) were incorrectly using Node.js's path.resolve() to resolve relative file paths. This caused bugs with SSH runtimes because path.resolve() uses LOCAL filesystem semantics instead of REMOTE filesystem semantics. Bug: - path.resolve() resolves paths relative to the local machine's filesystem - For SSH runtimes, paths need to be resolved relative to the remote filesystem - This caused file operations to fail or access wrong paths on SSH remotes Fix: - Replace path.resolve() with runtime.normalizePath() in all file tools - normalizePath() handles path resolution correctly for both local and SSH runtimes - LocalRuntime: uses Node.js path.resolve() (correct for local files) - SSHRuntime: uses POSIX-style path joining (correct for remote filesystems) Tests: - Added unit test to verify runtime.normalizePath() is used for path resolution - Added integration test for relative path handling in both local and SSH runtimes - All existing tests continue to pass Files changed: - src/services/tools/file_edit_operation.ts - src/services/tools/file_edit_insert.ts - src/services/tools/file_read.ts - src/services/tools/file_edit_operation.test.ts - tests/ipcMain/runtimeFileEditing.test.ts

- Remove unused import (beforeEach) - Use nullish coalescing operator (??) instead of logical or (||) - Properly type jest.fn() mocks to avoid any types
The test was mocking runtime.stat to reject, which caused the test to fail before assertions could run. Now properly mocks stat, readFile, and writeFile to return successful values so the test can verify normalizePath is called.

Problem
File editing tools were using Node.js
path.resolve()to resolve relative paths, which uses local filesystem semantics. For SSH runtimes, this caused incorrect path resolution because paths should be resolved relative to the remote filesystem.Solution
Replace
path.resolve()withruntime.normalizePath()which handles path resolution correctly for both local and SSH runtimes.Changes
