feat: support native installed Claude CLI detection

Add automatic detection for Claude CLI installed via native installer
(https://claude.ai/install.sh) which installs to ~/.local/bin/claude.

When claude is not found in PATH, the script now checks ~/.local/bin/claude
and adds it to PATH if found, with informative log messages.

Closes #303
