refactor: extract reserve_builder_tx_budget helper#476
Merged
Conversation
Move the 40-line inline block that reserves gas/DA/uncompressed-bytes budget for bottom-of-block builder txs into a named function in `builder_tx.rs`, alongside `BuilderTransactionCtx`. Adds unit tests covering empty input, bottom-only filtering, saturating sub, `None` DA, and uncompressed-limit reduction.
