Append two trailing spaces to each consecutive metadata line in the
header block of every codex file so the GitHub preview renders them
on separate lines instead of word-wrapping the whole block as one
paragraph. The last line before the blank-line/separator is left
alone since the blank line already breaks the paragraph.
Replaces old OpenAI/codex-cli.md and OpenAI/gpt-5.3-codex.md with a
structured OpenAI/codex/ folder: one file per model (12 models) plus
four personality files extracted from model_messages.instructions_variables
(friendly + pragmatic, with gpt-5.2-codex's slightly divergent variants
kept separate).
