Support CLAUDE_CONFIG_DIR env var for non-default config locations

[tkalus]

Problem

The local and all commands hardcode ~/.claude/projects as the path to find local Claude Code sessions. Users who store their Claude config in a non-default location (e.g. XDG-style paths, symlinked setups, or custom directories) have no way to point this tool at the right directory.

Claude Code itself respects the CLAUDE_CONFIG_DIR environment variable to override the default ~/.claude directory. This tool should do the same.

Proposed solution

Add a get_claude_config_dir() helper that checks os.environ.get("CLAUDE_CONFIG_DIR") and falls back to Path.home() / ".claude". Replace the two hardcoded Path.home() / ".claude" references in local_cmd and all_cmd with calls to this helper.

Specifically:

• local_cmd: projects_folder = Path.home() / ".claude" / "projects" becomes get_claude_config_dir() / "projects"
• all_cmd: source = Path.home() / ".claude" / "projects" becomes get_claude_config_dir() / "projects"
• Update the --source help text on the all command to mention the env var
• Update README to document the env var

Note

Scope is limited to the ~/.claude directory paths. ~/.claude.json is left unchanged since it already has --org-uuid as an explicit override.

I have a working implementation with tests and am happy to open a PR if this approach looks good.
