Merge R2-11 TagConfig consolidation (arch-review round 2) [PR #434]

Findings 01/C-1, 01/P-1 (single TagConfigIntent.Parse in Commons, 4 copies
delegate, parse-once) + 05 CONV-2/UNDER-1/UNDER-6 (shared strict TagConfigJson
readers, per-driver Inspect() + writable key, FOCAS capability pre-flight,
Modbus probe timeoutMs, deploy-gate Warn|Error). Phase C runtime-strict flip
deferred. T22/T24 deferred. Auto-merged AddressSpaceApplier.cs + DriverHostActor.cs
with R2-04/R2-10; verified OpcUaServer.Tests 286/286 + Runtime.Tests 396/396.
Build clean.
