fix(sync): also exclude orphan DB projects absent from config (#949)

Browse Source 
Address Codex review feedback. The previous path-only filter dropped an
implicit protection: get_project_mode() defaults projects missing from
config to CLOUD, so the old mode-based guard skipped stale DB rows that
had been removed from config. With a path-only check, an orphan row with
an absolute path would pass and background sync/watch could still mutate
a directory the user already removed from config (config is the source of
truth) if reconciliation was skipped or failed.

Introduce BasicMemoryConfig.is_locally_syncable(name, path), which
requires both config membership and an absolute path, and use it from
both the background sync selection and the watch cycle so the two paths
cannot diverge. Add direct unit tests for the helper plus an orphan-row
regression test for the watch selection.
