feat: header

[rkdud007]

What this PR enables

to narrow down the scope of online branch, for this specific PR targeted to implement header e2e functionality.

• 1. online mode : fetch mmr + header from indexer -> save in memorizer -> save in bincode file
• 2. zkvm mode : provided memorizer as input -> verify mmr -> finish

To be handled

• currently with conditional compilation logic, ideally we'd like to commit on zkvm program that get from any arbitrary local value defined in program.
• to make this program scaleable, we need sdk or cargo hdp run kind of format to abstract these multiple dependent flows in once.
• open question: to develop on zkvm mode -- as it currently on target os zkvm specified , it doesn't acknowledged by rust analyzer. i could manually turn on/off target os tobe zkvm on IDE side via modify setting , would like to know if theres any more convient way to switch on/off via some .cargo config files.
