The bd init and quickstart commands displayed outdated ID format
examples showing sequential IDs (prefix-1, prefix-2, ...) but beads
has used content-based hash IDs since bd-8e05.
Updated output now correctly shows:
Issues will be named: prefix-<hash> (e.g., prefix-a3f2dd)
This matches the actual GenerateHashID implementation in
internal/types/id_generator.go which generates 6-8 char hex hashes.
test(init): update test expectations to match hash-based ID format
Tests were checking for the old sequential format (prefix-1, prefix-2)
but the code now outputs hash-based format (prefix-<hash>).
