Update import/export to handle tombstones for deletion sync propagation:
Exporter:
- Include tombstones in JSONL output by setting IncludeTombstones: true
- Both single-repo and multi-repo exports now include tombstones
Importer:
- Tombstones from JSONL are imported as-is (they're issues with status=tombstone)
- Legacy deletions.jsonl entries are converted to tombstones via convertDeletionToTombstone()
- Non-tombstone issues in deletions manifest are still skipped (backward compat)
- purgeDeletedIssues() now creates tombstones instead of hard-deleting
This is Phase 2 of the tombstone implementation (bd-dli design), enabling
inline soft-delete tracking for cross-clone deletion synchronization.

* fix: use os.Lstat for symlink-safe mtime and permission checks
On NixOS and other systems using symlinks heavily (e.g., home-manager),
os.Stat follows symlinks and returns the target's metadata. This causes:
1. False staleness detection when JSONL is symlinked - mtime of target
changes unpredictably when symlinks are recreated
2. os.Chmod failing or changing wrong file's permissions when target
is in read-only location (e.g., /nix/store)
3. os.Chtimes modifying target's times instead of the symlink itself
Changes:
- autoimport.go: Use Lstat for JSONL mtime in CheckStaleness()
- import.go: Use Lstat in TouchDatabaseFile() for JSONL mtime
- export.go: Skip chmod for symlinked files
- multirepo.go: Use Lstat for JSONL mtime cache
- multirepo_export.go: Use Lstat for mtime, skip chmod for symlinks
- doctor/fix/permissions.go: Skip permission fixes for symlinked paths
These changes are safe cross-platform:
- On systems without symlinks, Lstat behaves identically to Stat
- Symlink permission bits are ignored on Unix anyway
- The extra Lstat syscall overhead is negligible
Fixes symlink-related data loss on NixOS. See GitHub issue #379.

* test: add symlink behavior tests for NixOS compatibility
Add tests that verify symlink handling behavior:
- TestCheckStaleness_SymlinkedJSONL: verifies mtime detection uses
symlink's own mtime (os.Lstat), not target's mtime (os.Stat)
- TestPermissions_SkipsSymlinkedBeadsDir: verifies chmod is skipped
for symlinked .beads directories
- TestPermissions_SkipsSymlinkedDatabase: verifies chmod is skipped
for symlinked database files while still fixing .beads dir perms
Also adds devShell to flake.nix for local development with go, gopls,
golangci-lint, and sqlite tools.
