Delete .github/dependabot.yml and update the two doc references that
pointed at it. Weekly grouped bumps were noise, and the #884 grouped
bump broke Bedrock streaming in prod; dependency updates are manual
and deliberate from now on. The @anthropic-ai/bedrock-sdk 0.29.1 exact
pin remains enforced by scripts/checks/no-new-antipatterns.mjs. Open
dependabot PRs #1083, #1082, #1012 closed alongside this change.
