Bumps [axios](https://github.com/axios/axios) from 1.13.5 to 1.16.1.

Release notes

v1.16.1 — May 13, 2026

This release ships a defence-in-depth fix for prototype pollution in formDataToJSON, hardens proxy and CI workflows, restores Webpack 4 compatibility for the fetch adapter, and includes several small bug fixes and maintenance improvements.

🔒 Security Fixes

Prototype Pollution Defence-in-Depth: Hardened formDataToJSON against already-polluted Object.prototype by walking own properties only, so attacker-controlled keys inherited from a poisoned prototype cannot propagate through deserialization. (#7413)

Proxy Cleartext Leak: Fixed an issue where HTTPS request data could be transmitted in cleartext to an HTTP proxy under certain configurations. (#10858)

CI Cache Removal: Removed all GitHub Actions caches as a defence-in-depth measure against cache poisoning vectors in the build pipeline. (#10882)

🐛 Bug Fixes

Data URI Parsing: Updated the fromDataURI regex to match RFC 2397 more strictly, fixing edge cases in data: URL handling. (#10829)

Unicode Headers: Preserved Unicode header values when running through request interceptors, so non-ASCII header content is no longer corrupted before dispatch. (#10850)

XHR Upload Progress: Guarded against malformed ProgressEvent payloads emitted by some environments during XHR upload, preventing crashes when loaded / total are missing or invalid. (#10868)

Webpack 4 Fetch Adapter: Fixed an "unexpected token" error caused by syntax in the fetch adapter that Webpack 4 could not parse, restoring compatibility for legacy bundler users. (#10864)

Type Definitions: Made parseReviver context.source optional in the type definitions to align with the ES2023 specification. (#10837)

URL Object Support Reverted: Reverted the change that allowed passing a URL object as config.url (originally #10866) due to regressions; this support will be reintroduced in a later release once the underlying issues are addressed. (#10874)

🔧 Maintenance & Chores

Cycle Detection Refactor: Replaced the array-based cycle tracker in toJSONObject with a WeakSet, improving performance and memory behaviour on large nested structures. (#10832)

composeSignals Cleanup: Refactored composeSignals to use a clearer early-return structure, simplifying the cancellation/abort composition path. (#10844)

AI Readiness & Repo Docs: Added AGENTS.md and related contributor-guide updates for both human and AI agents, plus post-release documentation improvements. (#10835, #10841)

Docs Improvements: Clarified the GET request example, fixed the interceptor eject example to reference the correct instance, and corrected the Buzzoid sponsor description in the README. (#10836, #10853, #10856)

Sponsorship Tooling: Fixed empty sponsor arrays in the sponsor processing script, added the ability to inject additional sponsors, updated the sponsorship link, and added a Twicsy advertisement entry. (#10843, #10859, #10869)

Dependencies: Bumped @commitlint/cli from 20.5.0 to 20.5.2. (#10846)
