fix(cli): preserve case in wordlist path parsing and use canonical paths

[rjvkn]

This PR improves handling of wordlist file paths in two ways:

1. Preserve Case in Paths
   Previously, the CLI parser lowercased the path portion of path[:key], causing failures on case-sensitive filesystems (e.g., Linux). Now the path is kept exactly as input, fixing these issues.

   

2. Resolve Canonical Paths
   We convert the provided path to its canonical form using PathBuf::canonicalize(). This resolves symlinks, relative components like . and .., and returns an absolute, normalized path. It ensures the file can be correctly found and accessed.

Why?

• Case preservation: Lowercasing paths broke access to files with uppercase letters in their names or directories.
• Canonicalization: Without resolving to canonical paths, relative paths or symlinked files could fail to open or cause inconsistent behavior.

Impact

• Fixes file-not-found errors caused by incorrect path casing.
• Enables correct handling of relative and symlinked paths.
• Makes wordlist file handling more robust and platform-compatible.
