fix: add correct ensv1 and ensv2 addresses to sepolia-v2 namespace

[shrugs]

Summary

• adds complete ENSRoot datasource config for sepolia-v2 (previously inherited from sepolia, which was incorrect)
• adds ReverseResolverRoot datasource with all reverse resolver addresses
• fixes ENSv2Root and ENSv2ETHRegistry contract addresses and start blocks to match the temp testing deployment

---

Why

• sepolia-v2 was incorrectly inheriting ensv1 addresses from the standard sepolia deployment
• the temp ensv2 testing deployment has its own dedicated ensv1 contracts that need to be indexed

---

Testing

• config-only change; addresses verified against deployment records
• will be validated during indexing of sepolia-v2 namespace

---

Notes for Reviewer (Optional)

• UniversalRegistrarRenewalWithReferrer uses zeroAddress as a placeholder since this contract doesn't exist in the sepolia-v2 deployment but is required by the registrars plugin and refactoring that is out-of-scope

📝 Walkthrough

Walkthrough

Refactored Sepolia v2 datasource to replace a namespace spread with explicit DatasourceNames entries: ENSRoot, ENSv2Root, ENSv2ETHRegistry, and ReverseResolverRoot. Added multiple root/shared ABIs and zeroAddress, updated contract addresses and unified startBlock 9374708 for ENSv2-related entries.

Summary

Sepolia v2 Datasource Restructuring packages/datasources/src/sepolia-v2.ts

Removed previous namespace spread and added explicit DatasourceNames mappings: ENSRoot, ENSv2Root, ENSv2ETHRegistry, ReverseResolverRoot. Imported new ABIs (BaseRegistrar, Registry variants, Resolver, NameWrapper, controllers, StandaloneReverseRegistrar, UniversalResolver, UniversalRegistrarRenewalWithReferrer) and zeroAddress. Added contract addresses and set startBlock 9374708 for new ENSv2 entries; included placeholder zeroAddress for UniversalRegistrarRenewalWithReferrer.

Poem

🐇 I nudged the exports, neat and spry,

ABIs stacked beneath the sky,
StartBlocks set and addresses true,
A zero to hold a placeholder view,
🥕 Hooray — the Sepolia map is new.

Pull request overview

This pull request fixes the sepolia-v2 namespace configuration to use correct ENS v1 and v2 contract addresses for the testing deployment. The configuration was previously inheriting addresses from the standard Sepolia deployment, which was incorrect for this separate testing namespace.

Changes:

• Removed inheritance from Sepolia namespace and added complete ENSRoot datasource configuration with dedicated ENSv1 contract addresses for the sepolia-v2 testing deployment
• Added ReverseResolverRoot datasource with all reverse resolver contract addresses
• Updated ENSv2Root and ENSv2ETHRegistry contract addresses and start blocks to match the testing deployment

Greptile Overview

Greptile Summary

This PR fixes a critical configuration bug where the sepolia-v2 namespace was incorrectly inheriting ENSv1 contract addresses from the standard sepolia deployment instead of using the dedicated temp testing deployment addresses.

Key Changes:

• Removed inheritance from SepoliaNamespace (via spread operator) and defined complete standalone configuration
• Added complete ENSRoot datasource with all ENSv1 contracts specific to sepolia-v2 deployment (Registry, BaseRegistrar, NameWrapper, Controllers, UniversalResolver)
• Fixed ENSv2Root datasource: corrected RootRegistry startBlock from 9771022 to 9771261, and Resolver startBlock from 3702721 to 9770973
• Fixed ENSv2ETHRegistry datasource: updated ETHRegistrar address from 0xe37a1366c827d18dc0ad57f3767de4b3025ceac2 to 0x3334f0ebcbc4b5b7067f3aff25c6da8973690d54 and startBlock from 9843689 to 9772505
• Added new ReverseResolverRoot datasource with 7 reverse resolver contracts (DefaultReverseRegistrar, DefaultReverseResolver, and L2-specific resolvers for Base, Linea, Optimism, Arbitrum, and Scroll)

Impact:
This is a config-only change that ensures the indexer will track the correct smart contracts for the sepolia-v2 testing deployment. The previous configuration would have indexed the wrong contracts, leading to incorrect data.

Confidence Score: 4/5

• This PR is safe to merge with minimal risk as it only updates configuration values
• Configuration-only change with no runtime logic modifications. All contract addresses follow valid Ethereum address format (0x + 40 hex chars). The zeroAddress placeholder for UniversalRegistrarRenewalWithReferrer is properly documented and intentional. The changes align with the stated goal of fixing incorrect address inheritance.
• No files require special attention - this is a straightforward configuration update

In `@packages/datasources/src/sepolia-v2.ts`:
- Around line 32-89: The comment above the ENSRoot datasource incorrectly says
the placeholder UniversalRegistrarRenewalWithReferrer uses a startBlock of 0;
update that comment to reflect the actual implementation (startBlock: 9374708)
or explicitly note why the placeholder uses the Sepolia startBlock 9374708, so
the comment aligns with the UniversalRegistrarRenewalWithReferrer entry and the
startBlock property.
