fix(core): harden fusion.db pragmas against mid-write crashes

Browse Source 
Switch synchronous from NORMAL to FULL and restore the default
wal_autocheckpoint of 1000 (was 100). The aggressive checkpoint
cadence + NORMAL fsync left a wide window for torn pages whenever
a writer crashed mid-checkpoint, which is exactly what happened
when node:sqlite SIGSEGV'd inside pager_write and corrupted the
production db.

Harden `fusion.db` against process crashes: switch `PRAGMA synchronous` from `NORMAL` to `FULL` and restore the default `wal_autocheckpoint = 1000` (was 100). Repeated node:sqlite SIGSEGVs inside `pager_write` had been corrupting the db; the previous settings left a wide window for torn pages whenever a writer crashed mid-checkpoint. The small fsync cost is worth the durability win.
