Function generate_code_lenses 

pub fn generate_code_lenses(
    parse_result: &dyn ParseResult,
    content: &str,
    versions: VersionData<'_>,
    formatter: &dyn EcosystemFormatter,
    uri: &Uri,
    command_id: &str,
) -> Vec<CodeLens>

Zero or one lens for the document, bound to command_id.

Delegates to collect_update_all_edits for the count in the lens title — the same call the command handler makes to produce the edits it applies, so title N == edits applied holds by construction rather than by two implementations agreeing. Returns no lens when there is nothing to update: a permanent line-0 annotation on every up-to-date manifest would be noise.
