When Mole is called from GUI applications (e.g., SwiftUI apps), the
request_sudo_access() function would fail with '/dev/tty: Device not
configured' error because /dev/tty is not available in non-TTY contexts.
This commit adds automatic detection of the runtime environment and uses
macOS native password dialog (via osascript) when running in GUI mode,
while preserving all existing TTY behavior including Touch ID support.
Changes:
- Detect TTY availability before attempting terminal-based authentication
- Use osascript to display native password dialog in GUI mode
- Maintain backward compatibility with all terminal-based workflows
- Ensure secure password handling (unset after use)
Fixes commands like 'mole clean', 'mole optimize', 'mole purge' when
invoked from GUI applications.
- Replace parentheses with commas for supplementary info
- Use commas instead of em-dashes for separators
- Update bullet points from - to * in some contexts
- Improve version extraction regex with fallback logic
Remove -icanon mode from stty settings to fix password authentication
failures when passwords contain special characters like '.' or '@'.
The non-canonical mode (-icanon min 1 time 0) caused character loss
in Terminal.app. Using only -echo keeps canonical mode which provides
more reliable character handling across all terminal emulators.
