chore(github): add kodiak auto-merge configuration

[RedStar071]

Summary

• Adds Kodiak bot configuration to automate dependency PR merges
• Configures squash-merge strategy with PR title as the commit message
• Restricts auto-merge to minor and patch version bumps from Dependabot and Renovate; major upgrades require manual review via the semver:major blocking label

Type of Change

• Chore / configuration (no source code changes)

Test Procedure

No code changes — verifiable by checking the Kodiak bot picks up the config after merging and begins processing eligible dependency PRs automatically.

Pre-flight Checklist

• Config reviewed for correctness (blocking labels, automerge scope)
• No unrelated changes included

Summary by CodeRabbit

• Chores
  • Updated internal pull request automation configuration for improved merge workflow management.

Walkthrough

Adds .github/.kodiak.toml to configure Kodiak's PR merge behavior: squash merge method, pull request title for commit messages, HTML comment stripping, coauthor inclusion, blocking labels (blocked, in review, semver:major), disabled label-based automerge, and dependency automerge limited to minor/patch updates from dependabot and renovate.

Poem

🐇 A little TOML file, neat and small,
Squash those commits, one message for all!
Block the majors, let minors through,
Dependabot and Renovate, we trust you two.
The rabbit hops forward, merges done right! 🌿
