Bob.Hou 9956f13b35 fix(db): never TRUNCATE-checkpoint a live WAL (SIGBUS under traffic) (#14005)
* fix(db): never TRUNCATE-checkpoint a live WAL

A live TRUNCATE checkpoint rewrites the shared wal-index while other
processes hold it mapped; dereferencing the stale mapping SIGBUSes the
process. Two production crashes six hours apart, coredump stack in
better-sqlite3 native memcpy (issue #13973).

Remove the periodic TRUNCATE scheduler. Runtime checkpoints are
PASSIVE-only, which move pages without changing the wal-index geometry,
while TRUNCATE stays on the shutdown path where reclaiming the file is
safe. The 256MB size guard now warns instead of escalating to a live
TRUNCATE, busy PASSIVE ticks feed the persisted busy telemetry that the
TRUNCATE tick used to carry, and a positive
OMNIROUTE_WAL_TRUNCATE_INTERVAL_MS logs a one-time deprecation warning.

* fix(db): RESTART the WAL when it exceeds the size guard

The 256MB size guard only warned, so a live WAL could keep growing until
the next restart. wal_checkpoint(RESTART) starts a new WAL file without
rewriting the mapped wal-index, which is what SIGBUS'd the process when
we used TRUNCATE under traffic.

Related to #13973.

* docs: drop a fake TRUNCATE env name from the WAL guard row

Backticks around TRUNCATE made the env/docs checker treat it as a
variable. The VACUUM rows next to it were never part of this change
and are not in the base docs.
