feat: Enable Across support for perps deposits

[pedronfigueiredo]

Explanation

Re-enable Across for perps deposits by allowing the specific quote-time perpsDeposit route and normalizing Arbitrum USDC targets to Across’s new HyperCore USDC-PERPS direct-deposit token. Keep the change limited so only the supported perps deposit flow bypasses Across’s same-chain rejection and same-token quote skipping.

At quote-build time, transaction pay still represents the required asset as Arbitrum USDC, so Across sees sourceChainId === targetChainId and “same token” even though the real destination we need to quote is HyperCore 1337 + 0x2100...0000. If we do not bypass those checks for this narrow case, the request is filtered out before we ever rewrite it into the actual Across direct-deposit route.

Note

Medium Risk
Changes Across strategy request filtering and quote-shaping for perpsDeposit, including token/chain rewriting and bypassing same-token/same-chain skips; mistakes could misroute deposits or produce incorrect quote amounts.

Overview
Re-enables Across for a narrow perpsDeposit path by allowing same-chain Arbitrum USDC requests when they match a supported perps-direct-deposit shape, instead of rejecting them as same-chain swaps.

Adds a perps-specific normalization layer that rewrites quote requests to Across’s HyperCore direct-deposit route (chain/token + USDC 6→8 decimal amount conversion) and adjusts destination handling to produce no post-swap actions and use from as recipient. Also updates source-amount calculation to avoid skipping “same token” quotes for this perps+Across case, with expanded test coverage and changelog entry.
