implement feeDelegation

[koo-virtuals]

Note

Medium Risk
Adds a new per-token launch flag that changes who is authorized to call BondingV5.launch() and when AgentTax recipients can be updated, which can block launches or mis-route tax updates if misconfigured. Script changes are test/deploy tooling but may affect testnet deployment repeatability and env expectations.

Overview
Introduces a new isFeeDelegation per-token flag in BondingV5: preLaunch(...) now accepts/stores it, and launch() now requires a privileged launcher when the flag is set (same gate as other special launch types).

Extends AgentTaxV2.updateCreatorForSpecialLaunchAgents eligibility checks to include fee-delegation tokens by adding isFeeDelegation() to the BondingV5 interface.

Improves Uniswap V3 testnet deployment tooling by adding MockPositionDescriptor, deploying/reusing QuoterV2, and making deployUniswapV3TestnetLiquidity.ts fully env-driven (no auto-mocks, standardized env names, per-contract verify, and more structured logging). Minor script updates adjust hardcoded test addresses/amounts and add router/factory mismatch guidance.
