* feat(io): add pkg/io with symlink-safe path validation
- Add pkg/io with Medium interface for filesystem abstraction
- Add pkg/io/local with sandboxed filesystem implementation
- Add symlink-safe path validation to prevent bypass attacks
- Add sentinel errors (ErrPathTraversal, ErrSymlinkTraversal)
- Add NewSandboxed() for creating sandboxed Medium instances
- Add MockMedium for testing
Closes#169

* feat(io): extend Medium interface with Delete, Rename, List, Stat operations
Add missing filesystem operations to Medium interface:
- Delete(path) - removes file or empty directory
- DeleteAll(path) - removes path and contents recursively
- Rename(old, new) - moves or renames files/directories
- Exists(path) - checks if path exists
- IsDir(path) - checks if path is a directory
- List(path) - returns directory contents as []os.DirEntry
- Stat(path) - returns file info as os.FileInfo
Implements both local.Medium and MockMedium with full support.
Closes#102

* fix(io): MockMedium.Read returns os.ErrNotExist for consistency
Ensures os.IsNotExist(err) works with MockMedium like with real filesystem.

- Add WithWorkspaceRoot() option for configuring the workspace directory
- Add validatePath() helper to check paths are within workspace
- Apply validation to all file operation handlers
- Default to current working directory for security
- Add comprehensive tests for path validation
Closes#82

* refactor: move CLI commands from pkg/ to internal/cmd/
- Move 18 CLI command packages to internal/cmd/ (not externally importable)
- Keep 16 library packages in pkg/ (externally importable)
- Update all import paths throughout codebase
- Cleaner separation between CLI logic and reusable libraries
CLI commands moved: ai, ci, dev, docs, doctor, gitcmd, go, monitor,
php, pkgcmd, qa, sdk, security, setup, test, updater, vm, workspace
Libraries remaining: agentic, build, cache, cli, container, devops,
errors, framework, git, i18n, io, log, mcp, process, release, repos

* refactor(mcp): use pkg/io Medium for sandboxed file operations
Replace manual path validation with pkg/io.Medium for all file operations.
This delegates security (path traversal, symlink bypass) to the sandboxed
local.Medium implementation.
Changes:
- Add io.NewSandboxed() for creating sandboxed Medium instances
- Refactor MCP Service to use io.Medium instead of direct os.* calls
- Remove validatePath and resolvePathWithSymlinks functions
- Update tests to verify Medium-based behaviour

* fix: correct import path and workflow references
- Fix pkg/io/io.go import from core-gui to core
- Update CI workflows to use internal/cmd/updater path

* fix(security): address CodeRabbit review issues for path validation
- pkg/io/local: add symlink resolution and boundary-aware containment
- Reject absolute paths in sandboxed Medium
- Use filepath.EvalSymlinks to prevent symlink bypass attacks
- Fix prefix check to prevent /tmp/root matching /tmp/root2
- pkg/mcp: fix resolvePath to validate and return errors
- Changed resolvePath from (string) to (string, error)
- Update deleteFile, renameFile, listDirectory, fileExists to handle errors
- Changed New() to return (*Service, error) instead of *Service
- Properly propagate option errors instead of silently discarding
- pkg/io: wrap errors with E() helper for consistent context
- Copy() and MockMedium.Read() now use coreerr.E()
- tests: rename to use _Good/_Bad/_Ugly suffixes per coding guidelines
- Fix hardcoded /tmp in TestPath to use t.TempDir()
- Add TestResolvePath_Bad_SymlinkTraversal test

- pkg/runtime, pkg/webview, pkg/workspace, pkg/ws
- pkg/plugin, pkg/config, pkg/i18n, pkg/module
- pkg/crypt, pkg/io, pkg/process
Add pkg/errors with simple E() helper for error wrapping.
Update go.work to only include CLI-relevant packages.
CLI now builds with CGO_ENABLED=0 - no linker warnings.
