Add rename-prefix command (bd-420)

- Implement bd rename-prefix command with --dry-run and --json flags
- Add prefix validation (max 8 chars, lowercase, starts with letter)
- Update all issue IDs and text references atomically per issue
- Update dependencies, labels, events, and counters
- Fix counter merge to use MAX() to prevent ID collisions
- Update snapshot tables for FK integrity
- Add comprehensive tests for validation and rename workflow
- Document in README.md and AGENTS.md

Known limitation: Each issue updates in its own transaction.
A failure mid-way could leave mixed state. Acceptable for
intended use case (infrequent operation on small DBs).

Edge Cases\n- What happens if DetectCollisions() fails?\n- What if all issues are collisions?\n- What if JSONL is malformed?\n- Race conditions with concurrent auto-imports?\n\n### 3. User Experience\n- Is the warning message clear and actionable?\n- Should we log to a file instead of/in addition to stderr?\n- Should there be a --auto-resolve flag?\n\n### 4. Performance\n- Does collision detection add significant latency?\n- Will this work with 1000+ issues?\n- Any unnecessary N+1 queries?\n\n### 5. Testing Gaps\n- Do we need integration tests for collision scenarios?\n- Should we test the warning output?\n- Test autoImportWithoutCollisionDetection() fallback?\n\n## Questions for Reviewer\n1. Should auto-import be more aggressive (auto-resolve) or more conservative (fail)?\n2. Should we add a counter for how many times collisions occurred?\n3.

+### Renaming Prefix
+
+Change the issue prefix for all issues in your database. This is useful if your prefix is too long or you want to standardize naming.
+
+```bash
+# Preview changes without applying
+bd rename-prefix kw- --dry-run
+
+# Rename from current prefix to new prefix
+bd rename-prefix kw-
+
+# JSON output
+bd rename-prefix kw- --json
+```
+
+The rename operation:
+- Updates all issue IDs (e.g., `knowledge-work-1` → `kw-1`)
+- Updates all text references in titles, descriptions, design notes, etc.
+- Updates dependencies and labels
+- Updates the counter table and config
+
+**Prefix validation rules:**
+- Max length: 8 characters
+- Allowed characters: lowercase letters, numbers, hyphens
+- Must start with a letter
+- Must end with a hyphen (or will be trimmed to add one)
+- Cannot be empty or just a hyphen
+
+Example workflow:
+```bash
+# You have issues like knowledge-work-1, knowledge-work-2, etc.
+bd list  # Shows knowledge-work-* issues
+
+# Preview the rename
+bd rename-prefix kw- --dry-run
+
+# Apply the rename
+bd rename-prefix kw-
+
+# Now you have kw-1, kw-2, etc.
+bd list  # Shows kw-* issues
+```
