Upgrade to cluster definition v1.10

Description:

To fully support the new v1.10.0 cluster‐definition schema in our SDK (and downstream FE/LP), we need to establish sensible defaults and enforce validation rules on the following fields:

1. compounding

• Default: true
• Allowed values: true or false
• Note: Controls whether validator deposits are “compounded” (0x02) or simple (0x01), which in turn affects deposit defaults and validator type.

2. target_gas_limit

• Default: 36000000
• Validation: Must be a positive integer (> 0). [might not need since protocol already checks with uint?]

3.consensus_protocol

• Default: "" (empty string)
• Allowed values: "" or "qbft"
• Note: We only support “qbft” for now; any other input should be rejected.

4. deposit_amounts

• Default: null
• Validation:
  • If compounding === false (simple validators):
  • Must be either null or an array containing any subset of:
    • ["1000000000", "32000000000"]
    • (Corresponds to [1 ETH, 32 ETH] in wei-scale strings)
  • If compounding === true (compounded validators):
    • Must be either null or an array containing any subset of:
    • ["1000000000", "8000000000", "32000000000", "256000000000"]
    • (Corresponds to [1 ETH, 8 ETH, 32 ETH, 256 ETH])

Acceptance Criteria:

• SDK definitions default compounding to true and reject non-boolean inputs.
• SDK defaults target_gas_limit to 36000000; rejects zero or negative values.
• SDK defaults consensus_protocol to ""; rejects any string other than "" or "qbft".
• SDK defaults deposit_amounts to null; validates array entries against the correct set based on compounding.
• Unit tests covering each field’s default and validation behavior.
• Documentation updated (FE/LP README or spec) to reflect the new defaults and validation logic.

Start with the SDK's cluster-definition definitions and existing unit-test setup, then locate the FE/LP README or spec named in the issue. Cover each field's defaults, validation rules, conditional deposit sets, and invalid values in tests; done means the documentation matches and the unit tests pass.
