BET-553: Remove L2-related bridging code (#2)

* refactor: remove L2 bridging infrastructure for L1-only deployment

- Remove all L2 bridge code (src/L2/, src/common/bridge/)
- Remove bridge deployment scripts and tests
- Remove pre-migration script and related tests
- Remove ITokenObserver from PermissionedRegistry
- Remove ejector role from deployment configuration
- Refactor migration controllers to register directly to ETH_REGISTRY
- Create MigrationTypes.sol with TransferData and MigrationData structs
- Keep minimal BridgeRolesLib stub for ETHTLDResolver compatibility

BREAKING CHANGE: Cross-chain bridging functionality removed

* docs: update documentation to remove L1/L2 terminology

- Remove L2 Scalability, Cross-Chain Support, and ejection features
- Add Gas Efficiency feature instead
- Delete L2 Components section (dead links to removed files)
- Rename L1 Components to Core Components
- Update ETHTLDResolver docs to describe v1/v2 resolution
- Delete Cross-Chain Bridge section
- Simplify devnet docs to single chain
- Remove dead L2 file comments from deploy/constants.ts

Also includes directory restructuring:
- Flatten src/common/* and src/L1/* into src/
- Rename L1*MigrationController to *MigrationController
- Remove TOKEN_OBSERVER role and shift subsequent roles
- Delete BridgeRolesLib and L1BridgeController

* docs: improve README markdown formatting

* refactor: remove ejection and unregister functionality

Remove cross-chain ejection code and ROLE_UNREGISTER since migration
now means staying on the same chain but adding a name to the v2 registry.

- Remove POST_EJECTION state and branch from ETHTLDResolver
- Remove unregister() from PermissionedRegistry and IStandardRegistry
- Remove ROLE_UNREGISTER and ROLE_UNREGISTER_ADMIN constants
- Remove bridgeName() function from testNames.ts
- Delete ejection.test.ts and remove ejection tests
- Update migration controller tests to remove ROLE_UNREGISTER grants

* fix(ci): increase Node.js heap size for type checking

Add NODE_OPTIONS with 8GB max heap size to the check-types CI job
to prevent JavaScript heap out of memory errors when TypeScript
processes the large generated artifacts file.

* wip

* chore: wip

* fix: earlier issues

* fix: resolve TypeScript type errors and Solidity lint issues

- Simplify deployVerifiableProxy function signature to avoid complex
  EncodeFunctionDataParameters intersection type inference issues
- Fix Solidity import order in MigratedWrappedNameRegistry, UserRegistry,
  ETHTLDResolver, and LockedNamesLib to properly group parent and
  current directory imports
- Fix prettier formatting in DNSAliasResolver

* fix(ci): increase bun test timeout for e2e tests

Increase the timeout from default 5s to 30s to accommodate slower
devnet operations (EVM snapshot restoration and sync) on CI.

* refactor(resolver): remove pre-migration code from ETHTLDResolver

Remove all traces of pre-migration functionality which was used to
indicate names that hadn't migrated from V1 yet. This state (address 0x1)
is no longer needed.

Changes:
- Remove PRE_MIGRATION from NameState enum
- Remove _determineInflightResolver and _nameStateFrom functions
- Simplify getResolverCallback and resolveNamechainCallback to pure
- Update resolveNamechainCallback to directly revert UnreachableName
- Remove pre-migration file entries from .gitignore

* refactor: remove ETHTLDResolver and related deployment scripts

Remove the ETHTLDResolver contract which was used for unified
ENSv2/ENSv1 resolution. This includes:
- Delete ETHTLDResolver.sol contract
- Remove deploy scripts 04_ETHTLDResolver.ts and 05_SetETHTLDResolver.ts
- Remove ETHTLDResolver integration tests
- Update references in setup scripts, e2e tests, and documentation
