docs: normalize generated-file headers and prune obvious comments

The theme-studio and browser-choice generators now stamp their output with a header that names the authoritative source and says to regenerate rather than hand-edit. I regenerated both files to match. I also deleted six obvious "describe the next form" comments, replaced two stale placeholders in titlecase.el and an incomplete FIXME in org-checklist.el with real rationale, and condensed early-init's header and Commentary.
