Subject: [PATCH] feat: add claude-opus-4-6[1m] model with 1M context window
 (#288)

Add the 1M context variant of Claude Opus 4.6 to the model registry
and fix model resolver to try exact match before glob detection, so
model IDs containing bracket characters (like [1m]) are not
misinterpreted as glob patterns.
