Pre-merge author checklist

I've followed MetaMask Contributor Docs and MetaMask Extension Coding Standards.
I've completed the PR template to the best of my ability
I’ve included tests if applicable
I’ve documented my code using JSDoc format if applicable
I’ve applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Pre-merge reviewer checklist

I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Medium Risk
Expands Bridge/Swap functionality to a new chain and introduces new contract/token address constants, which could impact routing/quoting if misconfigured; changes are largely additive and covered by a selector test update.

Overview
Adds MegaETH as a supported network for Bridge and Swaps by wiring CHAIN_IDS.MEGAETH_MAINNET into the allowed chain lists and display-name maps, and defining MegaETH-specific default token/contract/wrapped-token addresses plus a USDT0 common pair.

Updates slippage/stablecoin detection to recognize MegaETH’s USDT0 asset, adjusts bridge selector tests to include the extra destination chain, and bumps @metamask/bridge-controller to ^65.3.0 (with lockfile updates).
