Creates a new analysis version for an existing code vault using its existing source settings. For LOCAL_AGENT, the response includes next_steps.commands and the local agent must be run again. For GIT/FILE_ARCHIVE, the re-analysis of the original code source is queued automatically. Note: summary/results/report tools always return the latest version only, so reanalysis replaces access to prior version data. Requires X-API-Key (existing users can generate an API key in the web app). If headers aren't supported, pass api_key in arguments.
