The parser keeps a condition's text, nativeCode, nativeSeverity, qualifier and type. A new
MTConnectConditionTracker applies MTConnect's multi-condition semantics (per-nativeCode
activation/clearing across /sample deltas, /current baseline reset, Unavailable), and
MTConnectConditionAlarmMapper turns tracker state into Part 9 transitions: Warning=500,
Fault=800, Normal=clear, Unavailable=inactive + BadNoCommunication; escalation or a new
code retriggers. The driver implements IAlarmSource keyed by the alarm tag's RawPath,
diffs against what the server was actually told (only when a handler is attached), so a
reconnect/re-baseline never re-raises an unchanged condition and a missed transition is
delivered on the next subscribe. Ack is a no-op success. Existing CONDITION String tags
are unchanged; a tag becomes an alarm only via the standard TagConfig 'alarm' object.
