Subject: [PATCH] feat(timeout): Add --timeout-elapsed for seamless dialog
 chaining

Adds a new --timeout-elapsed flag that allows progress bar continuation
across chained dialogs by specifying how much time has already elapsed.

Changes:
- Add timeout_elapsed field to YadData struct (yad.h)
- Register --timeout-elapsed CLI option (option.c)
- Update timeout_cb to initialize from elapsed value (main.c)
- Calculate initial progress bar fraction from elapsed time
- Update remaining time label to account for elapsed time

Usage:
  # First dialog
  yad --timeout=30 --timeout-indicator=bottom

  # Second dialog continuing same timeout (10s elapsed)
  yad --timeout=30 --timeout-elapsed=10 --timeout-indicator=bottom

The progress bar and remaining time label will start at the correct
position based on the elapsed time, enabling smooth visual continuity
when chaining multiple yad dialogs with a shared timeout budget.
