NicolasGB 7329e89a85 feat(terminal): add configurable cursor render delay for terminal buffers ...

Add cursor position restoration with configurable timing to handle terminal
     buffer rendering asynchronously. This fixes cursor column being reset to 0
     when refreshing jj log commands.

     Changes:
     - Add `terminal.cursor_render_delay` configuration option (default: 10ms)
     - Add buffer.get_cursor() and buffer.set_cursor() helpers in core/buffer
       * buffer.set_cursor() uses defer_fn with configurable delay for terminal buffers
       * Automatic position validation with clamping to buffer bounds
       * Line number clamped to [1, line_count]
       * Column clamped to [0, line_length] based on actual line content
       * Validation happens inside deferred callback to check against final rendered content
     - Extract clamp_cursor_position() helper to eliminate code duplication
     - Refactor terminal module to use new buffer cursor helpers
     - Store and restore cursor position when cycling through log commands
     - Update README with terminal configuration section and example usage

     The delay is necessary because nvim_open_term() + nvim_chan_send() have
     asynchronous rendering in the terminal emulator layer. Setting the cursor
     before rendering completes results in the column being reset to 0. Users
     experiencing issues can increase the delay value if needed.
