fix(cli): share Vault-relative path exclusions

Apply watcher and logical-target exclusions within the selected Vault so
hidden or database-like parent directories do not suppress monitoring.
Protect primary, previous, and view databases, and provide a runtime opt-in
for ordinary database-like directories without changing database ownership.

Cover hidden roots, symlink restarts, exclusion parity, and encrypted
CouchDB create, modify, and delete operations with regression tests.

+### Database-like directory exclusions
+
+By default, Vault synchronisation excludes path components ending in
+`-livesync-v2` or containing `-livesync-v2-mrview-` at every depth. These names
+cover the CLI's primary PouchDB directories and their view indexes. The same
+policy applies during startup scans, live monitoring, and target checks for
+received files.
+
+If an ordinary directory uses one of these names, specify `--include-db-like-dirs`
+on each invocation that should synchronise it:
+
+```bash
+livesync-cli ./database --vault ./vault --include-db-like-dirs daemon
+```
+
+The option does not override hidden-entry exclusions or `.livesync/ignore`.
+Direct database-like entries inside the configured `database-path` also remain
+excluded, including previous databases and view indexes. When `database-path`
+and the Vault are the same directory, the option can include matching names
+below ordinary subdirectories, but direct database-like entries remain protected.
+
+The option changes a naming rule; it does not inspect arbitrary directory
+contents. An unrelated database outside the configured database storage area
+can also be included by opting in. The option is not saved to settings.
+
 ### .livesync/ignore
 
 Place a `.livesync/ignore` file in your vault root to exclude files from sync in both directions (local → CouchDB and CouchDB → local).
