ci: add Claude-based version bump analysis for every push

Add scripts/analyze-bump.sh that sends the diff and commit log to
Claude Haiku to determine the appropriate semver bump (major/minor/patch).
Wired into semantic-release via @semantic-release/exec analyzeCommitsCmd.

The commit-analyzer still handles conventional commits; Claude acts as
a second opinion and ensures non-conventional commits also trigger a
release. semantic-release picks the highest bump from both.

Falls back to "patch" if ANTHROPIC_API_KEY is missing or the call fails.
