Neil 2579469201 perf(orchestration): cache the prepared statements the graph publish recompiles
SyncDatabase refuses to cache any `SELECT *` — node:sqlite can build the first
row after a schema change from stale column names — so every wildcard read in
the orchestration DB recompiles its SQL on each call. The graph publish runs
that fan-out once per pane, ~0.7 times a second, forever.

Add a per-connection prepared-statement cache scoped to the orchestration DB,
whose schema is frozen in the constructor (createTables/migrate/trigger) and
whose resets are DELETE-only, and route the buildByPaneKey -> getForHandle ->
getRecent path through it. 5 publishes over 2 panes: 30 compilations -> 2.
