feat: add glob pattern expansion to CLI find search paths and environment directories (Fixes #354)

[karthiknadig]

Expands glob patterns in search_paths and environment_directories when constructing the configuration for the find CLI command, using the expand_glob_patterns utility from pet-fs.

• Call expand_glob_patterns on search_paths and environment_directories in create_config()
• Uses the glob expansion introduced in Add missing CLI arguments for find and resolve commands (with env var fallbacks) #353

Fixes #354

Pull request overview

Adds CLI parity with the JSONRPC server by expanding glob patterns in pet find configuration inputs, so quoted globs and env-var-provided globs work as expected.

Changes:

• Expand glob patterns in search_paths when building Configuration for the CLI find command.
• Expand glob patterns in environment_directories when building Configuration.

• With glob expansion, search_paths can become empty when the user explicitly provides only glob patterns that match nothing (or invalid patterns). In that case this code will now fall back to adding cwd, which changes the prior semantics where explicit search_paths disabled the default cwd behavior. Consider only defaulting to cwd when options.search_paths is None (not provided), not when it was provided but expanded to zero matches.

    if search_paths.is_empty() {
        if let Ok(cwd) = env::current_dir() {
            search_paths.push(cwd);
        }
    }
