Implement AttachmentFields to track molecule attachments on pinned/handoff beads:
- AttachedMolecule: root issue ID of attached molecule
- AttachedAt: timestamp when attached
API:
- AttachMolecule(pinnedBeadID, moleculeID) - attach
- DetachMolecule(pinnedBeadID) - detach
- GetAttachment(pinnedBeadID) - query
- ParseAttachmentFields(issue) - parse from description
- FormatAttachmentFields(fields) - format for description
Includes comprehensive tests for parsing and API.

Fix ~50 errcheck warnings across the codebase:
- Add explicit `_ =` for intentionally ignored error returns (cleanup,
best-effort operations, etc.)
- Use `defer func() { _ = ... }()` pattern for defer statements
- Handle tmux SetEnvironment, KillSession, SendKeysRaw returns
- Handle mail router.Send returns
- Handle os.RemoveAll, os.Rename in cleanup paths
- Handle rand.Read returns for ID generation
- Handle fmt.Fprint* returns when writing to io.Writer
- Fix for-select with single case to use for-range
- Handle cobra MarkFlagRequired returns
All tests pass. Code compiles without errors.
