feat: add grove-with-delegation strategy [grove-with-delegation]

[ChaituVR]

Summary

Adds the grove-with-delegation strategy for Grove protocol governance. (From telegram group)

Voting power is the actively staked GROVE balance — activeBalanceOf of an account in the stGROVE vault (0xF3Ddcaa3BD5D04ba08beC69cf34D9d9C9c112d14). Using activeBalanceOf (rather than slashableBalanceOf) excludes stake that has already been requested for withdrawal, so an account queued to exit cannot keep voting power.

It reuses the same delegation model as the existing spark-with-delegation strategy:

• Non-delegators get their own actively staked balance.
• Whitelisted delegates (whitelistedDelegates param) get their own balance plus any delegated balance.
• Non-whitelisted delegates get only their own balance (delegations to them don't count).
• Delegators get 0 (power transfers to their delegate).

The only structural difference from spark-with-delegation is the token config: grove reads a single contract-call (activeBalanceOf) instead of erc20-balance-of + slashableBalanceOf.

Parameters

• whitelistedDelegates (optional): addresses that should receive delegated balance. Empty/omitted → no address receives delegated balance.
• symbol (optional): display symbol (defaults to stGROVE).

Note on CI

The strategy test currently fails the "at least 1 address with a positive score" check. This is a data, not code, issue: at the time of writing, the stGROVE vault has zero total supply on mainnet (verified at the example block and at chain head — totalSupply() and activeBalanceOf/balanceOf for all example addresses return 0). Once stGROVE has real stakers, examples.json needs to be updated with a block + addresses that carry a positive activeBalanceOf, and the suite will pass.

Reviewed. CI failure is the known no-transactions-on-new-contracts case per Chaitu: all 8 test-strategy failures are the empty/no-positive-score assertions because the stGROVE vault currently has zero total supply on mainnet (at the example block and at head). Lint and the main test suite pass. Clean, self-contained strategy add mirroring spark-with-delegation, no red flags. examples.json should be refreshed with a positive-balance block once stGROVE has stakers.
