chore: sync bounty board data

[github-actions]

Regenerated src/data/bounties.generated.json from the bounty-labelled issues. Opened by the Sync bounty board data workflow.

Review the diff before merging — these are the rewards that go live on the public bounty board.

Superseded by #219, which carries the identical bounties.generated.json content.

This PR cannot merge: the workflow commits as github-actions[bot], which fails verification/cla-signed and cannot produce a verified signature, both of which the base branch requires. #219 is the same diff recommitted under a CLA-covered, GPG-signed author.

Closing so the sync branch is free for the next dispatch. The workflow itself still needs fixing so this is not manual each time.
