Commit Message

fix: MCP stress findings: explore fan-out, auth check, output size, quality

Explore walks breadth-first with one bulk /objects/related call per level
(was one call per node, unbounded; one timeout aborted the walk), with a
node budget and per-node errors; maxDepth 0 now means unlimited. Connect
verifies the token on /v1/namespaces (/v1/info is public) and keeps the
current token on re-connect. elementIds are deduplicated (max 100), tool
results are capped with a narrowing hint, over-long suggestion queries skip
fuzzy matching.

Server side: a component history read failure now carries a 501
responseDetail instead of an empty series, and OPC UA status maps to quality
by severity, so UncertainInitialValue (unused alarm sub-states) is no longer
Bad and pseudo-session no longer leaks status names as quality.
