[Protocol] MVP implementation off the on-chain CreateClaim message handling

[Olshansk]

Objective

MVP Implementation of CreateClaim to enable Shannon TestNet.

Origin Document

• [Miner] chore: scaffold create-claim message #43

Goals

• Enable E2E validation of the entire protocol
• Unblock iterative development of the claim & proof lifecycle
• Unblock iterative development of on-chain tokenomics

Deliverables

• A single PR that introduces the business logic for the on-chain CreateClaim message (verification, etc...)
• A single PR that updates the CLI to submit CreateClaim messages
• Introduce make targets to enable development (visibility, triggering, debugging , etc...) of on-chain claims
• Add extensive unit tests (moved to [Testing] Ensure unit test coverage of supplier module #362)

Non-goals / Non-deliverables

• Account Management (i.e. Burn & Mint) business logic related to the Claim & Proof lifecycle (leave TODOs)
• Governance Params necessary for the Claim & Proof lifecycle (leave TODOs)

General deliverables

• Comments: Add/update TODOs and comments alongside the source code so it is easier to follow.
• Testing: Add new tests (unit and/or E2E) to the test suite.
• Makefile: Add new targets to the Makefile to make the new functionality easier to use.
• Documentation: Update architectural or development READMEs; use mermaid diagrams where appropriate.

@bryanchriswhite Picking this up

[Olshansk]

@bryanchriswhite I'm unassigning myself from this in the meantime and will let you pick it up.

I think the comments you left (copy-pastedbelow) in func (k msgServer) CreateClaim(goCtx context.Context, msg *types.MsgCreateClaim) is a great starting point!

	/*
		TODO_INCOMPLETE: Handling the message

		## Validation

		### Session validation
		1. [ ] claimed session ID matches on-chain session ID
		2. [ ] this supplier is in the session's suppliers list

		### Msg distribution validation (depends on session validation)
		1. [ ] governance-based earliest block offset
		2. [ ] pseudo-randomize earliest block offset

		### Claim validation
		1. [ ] session validation
		2. [ ] msg distribution validation

		## Persistence
		1. [ ] create claim message
			- supplier address
			- session header
			- claim
		2. [ ] last block height commitment; derives:
			- last block committed hash, must match proof path
			- session ID (?)

@bryanchriswhite I'm closing this out and we'll create new tickets to capture any missing work.

@Olshansk I had the same thought and opened #362. 👍
