v0.2.0

Added

• Added automatic multi-request --keep filtering when results exceed one Codex prompt.
• Added RGK_TOTAL_PROMPT_MAX_BYTES and RGK_CODEX_CONCURRENCY keep-mode controls.

Changed

• Changed RGK_PROMPT_MAX_BYTES to limit each Codex request instead of failing the whole keep run.

Removed

• Removed RGK_KEEP_LIMIT; keep mode is now bounded by prompt byte budgets.

Fixed

• None.
