feat(mol): filter ephemeral issues from JSONL export (bd-687g)

Ephemeral issues should never be exported to issues.jsonl. They exist only
in SQLite and are shared via .beads/redirect pointers. This prevents
"zombie" issues from resurrecting after mol squash deletes them.

Changes:
- Filter ephemeral issues in autoflush, export, and multirepo_export
- Add --summary flag to bd mol squash for agent-provided summaries
- Fix DeleteIssue to also remove comments (missing cascade)
- Add tests for ephemeral filtering and comment deletion

   4. Creates a non-ephemeral digest issue
   5. Deletes the ephemeral children (unless --keep-children)
 
+AGENT INTEGRATION:
+Use --summary to provide an AI-generated summary. This keeps bd as a pure
+tool - the calling agent (Gas Town polecat, Claude Code, etc.) is responsible
+for generating intelligent summaries. Without --summary, a basic concatenation
+of child issue content is used.
+
 This is part of the ephemeral workflow: spawn creates ephemeral issues,
 execution happens, squash compresses the trace into an outcome.
 
 Example:
-  bd mol squash bd-abc123              # Squash molecule children
+  bd mol squash bd-abc123              # Squash with auto-generated digest
   bd mol squash bd-abc123 --dry-run    # Preview what would be squashed
-  bd mol squash bd-abc123 --keep-children  # Create digest but keep children`,
