New reminder kinds exist but emit nothing unless a feature check passes.

What

The system that injects short notes into the transcript gained kinds for environment, model, output style instructions, session context, date and language changes. All sit behind one feature check and emit a note only when the change parses cleanly, so nothing appears unless that check passes.

Evidence

output_style_instructions: (e) => {

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
