bd init: Default to YES for git hooks and merge driver

Fixes bd-bxha

Previously, bd init prompted users to install git hooks and merge driver,
which could result in incomplete setup if declined. Changed to install
both by default for better out-of-the-box experience.

Changes:
- Install git hooks automatically unless --skip-hooks is passed
- Install merge driver automatically unless --skip-merge-driver is passed
- Remove interactive prompts (no longer needed)
- Add warning messages on failure with suggestion to run bd doctor --fix
- Add --skip-hooks flag for explicit opt-out

Users who want to skip installation can now use:
  bd init --skip-hooks --skip-merge-driver
