fix: skip auto-repeat pile-up after injection, prevent stuck keys

- After each Unicode injection, skip next 10 events (auto-repeat backlog)
- Prevents 'rrrrrrrrrrrrrr' and '555555' from auto-repeat during injection delay
- Also fixes Ctrl+V/Ctrl+C clipboard conflict during injection window

CHANGELOG: document v0.1.1 Telex fixes, injection improvements, AppImage flags
