a794f6b55f feat(deploy): add pure-Go Ansible executor and Coolify API integration
Implement infrastructure deployment system with:

- pkg/ansible: Pure Go Ansible executor
  - Playbook/inventory parsing (types.go, parser.go)
  - Full execution engine with variable templating, loops, blocks,
    conditionals, handlers, and fact gathering (executor.go)
  - SSH client with key/password auth and privilege escalation (ssh.go)
  - 35+ module implementations: shell, command, copy, template, file,
    apt, service, systemd, user, group, git, docker_compose, etc. (modules.go)

- pkg/deploy/coolify: Coolify API client wrapping Python swagger client
  - List/get servers, projects, applications, databases, services
  - Generic Call() for any OpenAPI operation

- pkg/deploy/python: Embedded Python runtime for swagger client integration

- internal/cmd/deploy: CLI commands
  - core deploy servers/projects/apps/databases/services/team
  - core deploy call <operation> [params-json]

This enables Docker-free infrastructure deployment with Ansible-compatible
playbooks executed natively in Go.

ba7fa42522 feat(rag): add Go RAG implementation with Qdrant + Ollama
Add RAG (Retrieval Augmented Generation) tools for storing documentation
in Qdrant vector database and querying with semantic search. This replaces
the Python tools/rag implementation with a native Go solution.

New commands:
- core rag ingest [directory] - Ingest markdown files into Qdrant
- core rag query [question] - Query vector database with semantic search
- core rag collections - List and manage Qdrant collections

Features:
- Markdown chunking by sections and paragraphs with overlap
- UTF-8 safe text handling for international content
- Automatic category detection from file paths
- Multiple output formats: text, JSON, LLM context injection
- Environment variable support for host configuration

Dependencies:
- github.com/qdrant/go-client (gRPC client)
- github.com/ollama/ollama/api (embeddings API)

691908aa6c chore(io): migrate filesystem operations to io.Local abstraction (#247)
* feat(devops): migrate filesystem operations to io.Local abstraction

Migrate config.go:
- os.ReadFile → io.Local.Read

Migrate devops.go:
- os.Stat → io.Local.IsFile

Migrate images.go:
- os.MkdirAll → io.Local.EnsureDir
- os.Stat → io.Local.IsFile
- os.ReadFile → io.Local.Read
- os.WriteFile → io.Local.Write

Migrate test.go:
- os.ReadFile → io.Local.Read
- os.Stat → io.Local.IsFile

Migrate claude.go:
- os.Stat → io.Local.IsDir

Updated tests to reflect improved behavior:
- Manifest.Save() now creates parent directories
- hasFile() correctly returns false for directories

Part of #101 (io.Medium migration tracking issue).

Closes #107

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* chore(io): migrate remaining packages to io.Local abstraction

Migrate filesystem operations to use the io.Local abstraction for
improved security, testability, and consistency:

- pkg/cache: Replace os.ReadFile, WriteFile, Remove, RemoveAll with
  io.Local equivalents. io.Local.Write creates parent dirs automatically.
- pkg/agentic: Migrate config.go and context.go to use io.Local for
  reading config files and gathering file context.
- pkg/repos: Use io.Local.Read, Exists, IsDir, List for registry
  operations and git repo detection.
- pkg/release: Use io.Local for config loading, existence checks,
  and artifact discovery.
- pkg/devops/sources: Use io.Local.EnsureDir for CDN download.

All paths are converted to absolute using filepath.Abs() before
calling io.Local methods to handle relative paths correctly.

Closes #104, closes #106, closes #108, closes #111

* chore(io): migrate pkg/cli and pkg/container to io.Local abstraction

Continue io.Medium migration for the remaining packages:

- pkg/cli/daemon.go: PIDFile Acquire/Release now use io.Local.Read,
  Delete, and Write for managing daemon PID files.
- pkg/container/state.go: LoadState and SaveState use io.Local for
  JSON state persistence. EnsureLogsDir uses io.Local.EnsureDir.
- pkg/container/templates.go: Template loading and directory scanning
  now use io.Local.IsFile, IsDir, Read, and List.
- pkg/container/linuxkit.go: Image validation uses io.Local.IsFile,
  log file check uses io.Local.IsFile. Streaming log file creation
  (os.Create) remains unchanged as io.Local doesn't support streaming.

Closes #105, closes #107

* fix: address CodeRabbit feedback - use errors.E for context

Add contextual error handling using errors.E helper as suggested:
- config.go: Wrap LoadConfig read/parse errors
- images.go: Wrap NewImageManager, loadManifest, and Manifest.Save errors

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(io): add contextual error handling with E() helper

Address CodeRabbit review feedback by wrapping raw errors with the
errors.E() helper to provide service/action context for debugging:

- pkg/cache: wrap cache.New, Get, Set, Delete, Clear errors
- pkg/devops/test: wrap LoadTestConfig path/read/parse errors
- pkg/cli/daemon: wrap PIDFile.Release path resolution error
- pkg/container/state: wrap LoadState/SaveState errors
- pkg/container/templates: wrap GetTemplate embedded/user read errors

* chore(io): migrate internal/cmd/dev to io.Local abstraction

- Replace os.Stat with io.Local.Stat in cmd_file_sync.go
- Update test file to use io.Local.EnsureDir and io.Local.Write
- Add filepath.Abs for proper path resolution before io.Local calls

Closes #114

* chore(io): Migrate internal/cmd/docs/* to Medium abstraction

Fixes #113

* chore(io): Migrate internal/cmd/dev/* to Medium abstraction

Fixes #114

* chore(io): Migrate internal/cmd/setup/* to Medium abstraction

* chore(io): Complete migration of internal/cmd/dev/* to Medium abstraction

* feat(io): extend Medium interface with Delete, Rename, List, Stat operations

Adds the following methods to the Medium interface:
- Delete(path) - remove a file or empty directory
- DeleteAll(path) - recursively remove a file or directory
- Rename(old, new) - move/rename a file or directory
- List(path) - list directory entries (returns []fs.DirEntry)
- Stat(path) - get file information (returns fs.FileInfo)
- Exists(path) - check if path exists
- IsDir(path) - check if path is a directory

Implements these methods in both local.Medium (using os package)
and MockMedium (in-memory for testing). Includes FileInfo and
DirEntry types for mock implementations.

This enables migration of direct os.* calls to the Medium
abstraction for consistent path validation and testability.

* chore(errors): create deprecation alias pointing to pkg/log

Makes pkg/errors a thin compatibility layer that re-exports from pkg/log.
All error handling functions now have canonical implementations in pkg/log.

Migration guide in package documentation:
- errors.Error -> log.Err
- errors.E -> log.E
- errors.Code -> log.NewCode
- errors.New -> log.NewError

Fixes behavior consistency:
- E(op, msg, nil) now creates an error (for errors without cause)
- Wrap(nil, op, msg) returns nil (for conditional wrapping)
- WrapCode returns nil only when both err is nil AND code is empty

- 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,

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(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
