feat: resolve relative paths against session cwd in all file endpoints

All LLM-exposed file endpoints (list_files, read_file, write_file,
display_file, replace_file_content, grep_search, glob_search) now
read the X-Session-Id header and resolve relative paths against the
session's working directory instead of always using fs.home.

- Added optional cwd parameter to UserFS.resolve_path()
- Relative paths join against cwd if provided, else fs.home
- Absolute paths are unaffected
- execute endpoint also resolves relative cwd param against session cwd

+- 🗂️ **Session-aware relative path resolution** — all LLM-exposed file endpoints (`list_files`, `read_file`, `write_file`, `display_file`, `replace_file_content`, `grep_search`, `glob_search`) now read the `X-Session-Id` header and resolve relative paths (e.g. `.`) against the session's working directory instead of always defaulting to `fs.home`. Added an optional `cwd` parameter to `UserFS.resolve_path()` to support this. Absolute paths are unaffected.
