m1ngsama ea71b0ca02 feat: Add inline link display and vim-style quick navigation 
Major improvements to link handling and navigation:

Features:
- Display links inline with numbered indicators [0], [1], etc.
- Quick navigation: type number + Enter to jump to link
- Fast follow: press 'f' + number to open link directly
- Visual improvements: links shown with underline and highlight
- Remove separate link list at bottom for better readability

Technical changes:
- Add InlineLink structure to track link positions in text
- Implement wrap_text_with_links() for intelligent text wrapping
- Add GOTO_LINK and FOLLOW_LINK_NUM actions
- Implement LINK input mode for 'f' command
- Character-by-character rendering for proper link highlighting
- Update help documentation with new navigation methods

Usage examples:
- 3<Enter>  : Jump to link 3
- f5 or 5f  : Open link 5 directly
- Tab/Enter : Traditional navigation still works

All comments converted to standard Unix style (English).

Quick Link Navigation Guide

The browser now supports vim-style quick navigation to links!

Features

1. Visual Link Numbers

All links are displayed inline in the text with numbers like [0], [1], [2], etc.

  • Links are shown with yellow color and underline
  • Active link (selected with Tab) has yellow background

2. Quick Navigation Methods

Method 1: Number + Enter

Type a number and press Enter to jump to that link:

3<Enter>     - Jump to link [3]
10<Enter>    - Jump to link [10]

Method 2: 'f' command (follow)

Press f followed by a number to immediately open that link:

f3           - Open link [3] directly
f10          - Open link [10] directly

Or type the number first:

3f           - Open link [3] directly
10f          - Open link [10] directly

Method 3: Traditional Tab navigation (still works)

Tab          - Next link
Shift-Tab/T  - Previous link
Enter        - Follow current highlighted link

Examples
