Interactive Session Resume with Search and Filtering

What: When resuming previous sessions, you can now search through sessions and filter by git branch to quickly find what you're looking for.

How to use:

# Start claude code

# Press Ctrl+R to open session resume
# Then:
# - Press 'B' to toggle filtering by current git branch
# - Press '/' to enter search mode
# - Type to search across session summaries and branch names
# - Press Escape or Enter to exit search mode

Details:

• Search is case-insensitive and matches against session summary, first prompt, and git branch

• Visual feedback shows active filters and search term with a cursor indicator
• Context-aware help text shows available commands based on current mode
