Part of #44. Based on dev, independent, one line.

On the perf VM, after a cold fill and a few harness storms, a 100,000-note Home kept a 127 MB meta.db-wal next to its 240 MB list store. SQLite leaves the write-ahead log at the size of the biggest transaction it ever held. The big ones are a cold fill's 4,096-note batches, and with #372 the final index build.

PRAGMA journal_size_limit = 8388608 on the list store's connection cuts the log back to 8 MB whenever a checkpoint resets it. The search index already does the same (crates/search/src/index.rs).

cargo test -p calternal-notes (169) is clean.

SQLite leaves a write-ahead log at the size of the biggest transaction it
ever held: on the perf VM a 100,000-note Home kept a 127 MB meta.db-wal
beside its 240 MB list store, after a cold fill and a few storms. With
journal_size_limit it's cut back to 8 MB whenever a checkpoint resets
it. (#44)
