clawbot 594e7a504b Bound SQLite memory across the whole connection pool (closes #8)
The 3 GiB page cache and temp_store=MEMORY were set once in Initialize, so
only one pooled connection carried them and the other nine got no busy_timeout,
which drove many "database is locked" errors.

Move the per-connection settings into the DSN so every pooled connection gets a
64 MiB cache (640 MiB worst case over ten connections), synchronous OFF, a
5 s busy_timeout and WAL. Drop those pragmas from Initialize; DISTINCT temp
B-trees now spill to disk. Add process-wide soft (1 GiB) and hard (1.5 GiB)
heap limits; at the hard limit a statement returns SQLITE_NOMEM and the
existing batch paths log and drop, so nothing panics or exits.
