Merges 8 V1 plugins into 1 unified plugin, adds 4 new components (dep, tst, sec, rvr). 12 sub-modes: arc, eng, do, dbg, xdb, sdb, ndb, ctx, dep, tst, sec, rvr. L1 code-level guarantees: atomic writes, file locks, evidence gating, forced debug routing, 3-phase arc gate, evidence-first debug gate, Chinese language lock, scheduler boundary.
