chore(fullscreen): drop inline rationale comments, bump copyright to 2026

Addresses review feedback: the explanatory block comments in
FullscreenProvider (source-of-truth rationale, CoreTransport typing
note) were noise — the same context already lives in the PR
description and commit history. Copyright headers on the four new
files were carried over from the template at 2023; bumped to 2026.
