Two review findings, both real.
`attach_datatable_parses_name_and_role` never compiled: `parse_attach_datatable`
returns `Result<Option<_>>` now and one call site kept a single `unwrap`. Its
`?Role=analytics` case also asserted a refusal, contradicting the parser in the
same commit, which matches the key case-insensitively. Replaced with the cases
that are genuinely malformed, and a positive one for the cased key.
`-- role: analytics` fell through to the default role — the silent fallback the
strict parser exists to remove, for the spelling most likely to be typed. The
keyword now accepts an optional colon, attached or spaced, while a word that
merely starts with it (`rolebased`) is still not an attempt.
