Remove unused axios dependency with multiple CVEs

[Copilot]

axios was declared as a dependency but never imported or used — all HTTP calls go through Node's native fetch. The unused package carried multiple unpatched CVEs (SSRF via absolute URL, credential leakage, DoS via __proto__ and unbounded response size).

Changes

• package.json / perplexity-ask/package.json: Remove axios from dependencies
• package-lock.json: Updated to reflect removal

Reviewer's Guide

This PR removes the unused axios runtime dependency (and its transitive tree with known CVEs) from the root and perplexity-ask package manifests, updating the lockfile accordingly so that all HTTP traffic continues to rely solely on Node’s native fetch API.
