chore: update package version to 0.1.3 and dependencies

[Vittitow]

• Bumped package version to 0.1.3.
• Updated dependency @circle-fin/x402-batching to version 3.0.2.
• Added mappings for Base Mainnet and Polygon Mainnet in gateway.ts.
• Enhanced tests to cover new mappings in gateway.spec.ts.

---

Note

Medium Risk
Upgrades @circle-fin/x402-batching to a new major version and expands chain mapping to mainnets, which could introduce subtle behavior/API changes in gateway/batching flows despite minimal local code changes.

Overview
Updates the package to 0.1.4 and upgrades @circle-fin/x402-batching from ^2.0.4 to ^3.0.2 (with corresponding lockfile changes).

Extends CAIP2_TO_GATEWAY_CHAIN in src/gateway.ts to include Base and Polygon mainnet (eip155:8453 → base, eip155:137 → polygon) and adds/updates gateway.spec.ts assertions to cover the new mappings.

Version mismatch between package.json and package-lock.json

Medium Severity

The package.json version is set to 0.1.4 while package-lock.json version is 0.1.3. The PR description states the intent is to bump to 0.1.3, but the two files disagree. This means the published package version won't match what the lock file records, and running npm install will cause the lock file to be modified unexpectedly.
