Pull request overview

Reworks the osToken redemption multiplier representation to use an integer basis-points (bps) field while keeping a derived Decimal multiplier available via a property on ProtocolConfig.

Changes:

• Replace os_token_redeem_multiplier: Decimal with os_token_redeem_multiplier_bps: int and add a computed os_token_redeem_multiplier property.
• Update protocol config building and test factories to use the new _bps field/key and default.
• Bump package version and extend .gitignore.
