feat: make customize easy

[lightsing]

1. make submodules group scroll public inputs
2. expose public inputs api, refactor pi hash api using default trait implementation

[Copilot]

Pull request overview

This PR restructures the public inputs API to improve customization by organizing Scroll-specific public input types under a scroll submodule and exposing a cleaner API surface. The refactoring separates the encoding of public inputs from their hashing, using default trait implementations for the hash functions.

Key Changes:

• Moved Scroll-specific public input types (batch, bundle, chunk) into a new public_inputs::scroll submodule
• Renamed methods from pi_hash_* to pi_* to return raw encoded bytes instead of hashes, with hash computation moved to default trait implementations
• Updated all import paths throughout the codebase to reference the new public_inputs::scroll::* locations
