* test(validation): add failing tests for hyphenated prefix parsing
Reproduces bug where `bd create --parent` fails for projects with
hyphenated prefixes like "bead-me-up" or "web-app".
Root cause: ValidateIDFormat splits on first hyphen, so:
"bead-me-up-3e9.1" → prefix "bead" (wrong, should be "bead-me-up")
The bug flow in create.go:
1. User runs: bd create "Child" --parent bead-me-up-3e9
2. GetNextChildID generates: bead-me-up-3e9.1
3. ValidateIDFormat extracts: "bead" (splits at first hyphen)
4. ValidatePrefix compares: "bead" vs "bead-me-up" → MISMATCH
Tests added:
- TestValidateIDFormat: 6 cases for hyphenated prefix IDs
- TestValidateIDFormat_ParentChildFlow: simulates exact --parent flow,
showing simple prefixes pass while hyphenated prefixes fail
Workaround: use --force flag to bypass prefix validation.
* fix(validation): support hyphenated prefixes in ValidateIDFormat
Use utils.ExtractIssuePrefix instead of naive first-hyphen splitting.
This fixes bd create --parent failing for projects with hyphenated
prefixes like "bead-me-up" or "web-app".
Before: "bead-me-up-3e9" → prefix "bead" (wrong)
After: "bead-me-up-3e9" → prefix "bead-me-up" (correct)
ExtractIssuePrefix uses smart heuristics: split on last hyphen,
check if suffix is hash-like (3-8 chars, alphanumeric, digits for 4+).
* Update internal/validation/bead_test.go
