Method compact_commit

nodedb/src/engine/sparse/inverted/compaction.rs:21–36

Atomically write a new merged FTS segment and remove the source segments that were merged into it, in one redb write transaction. Crash-safe: if the process terminates before the commit, the original segments remain intact for the next maintenance pass. The single transaction also guarantees that no reader observes both the new and the old segments simultaneously.
