This commit introduces a new scramble option to help reduce distractions
during development by scrambling text using rot13. When enabled via the
new `--scramble` flag, text displayed in various views is transformed,
making it easier to focus on layout and behavior without reading the
actual content.
App & Args Updates
- Added a `scramble: bool` field to the main application state (in `app.rs`).
- Extended argument parsing (in `args.rs`) to recognize the `--scramble` flag.
NoteOptions Enhancement
- Introduced a new bit flag `scramble_text` in `NoteOptions` with
corresponding setter/getter methods.
UI Adjustments
- Propagated the scramble flag through note rendering functions across
navigation, timeline, and note view modules.
- Updated several UI components (e.g., in `nav.rs`, `route.rs`, and
`contents.rs`) to accept and apply the new note options.
Rot13 Implementation
- Implemented a helper function (`rot13`) to scramble text
conditionally when the scramble option is enabled.
This feature is intended for development builds only, offering a way to
obscure text content during UI tweaks and testing.
