fix(lanes): capitalize Vietnamese action-button labels, gitignore .ccam/

action.start/stop/clear/forget/purge/remove/reset in lanes.json (vi)
were lowercase (bắt đầu, dừng...) while every other button label in the
app capitalizes its first letter. Also gitignore /.ccam/ - the local
lane profile that appears in a repo's own working tree only when that
repo is adopted as its own lane (machine-specific runtime config, not
source).
