Request: collaborator access to contribute bug fixes (Frank-zhu0404)

[Frank-zhu0404]

Summary

Hi maintainers — I'd like to request repository collaborator access for GitHub user Frank-zhu0404.

Per CONTRIBUTING.md, code/docs PRs are currently accepted only from collaborators. I have a short list of small, already-scoped bug fixes I'd like to submit as proper PRs once access is granted.

Proposed first PRs (small / clear)

Issue	Scope
#143	README Download buttons are non-clickable images (docs-only; keep EN + ZH in sync)
#154	Offline smoke tests fail when ambient HTTP(S)_PROXY is set (CI harness)
#155	edit replace_all corrupts literal $ sequences
#153	MCODE_PROVIDER_API_KEY not stripped in scrub mode
#151	cloneContextWith drops isFile probe
#150	Bash deny rules skip transparent wrappers (allow does not)
#149	POST /api/file/save cannot create new files
#152	Context compaction trigger stays tripped after compaction

Happy to start with #143 (docs-only) and #154 (smoke/proxy) as the first two.

Validation I will run before any PR

• pnpm install --frozen-lockfile then pnpm verify (or pnpm verify --profile docs for docs-only)
• Fill the PR template (Change / Validation / publication checkboxes / maintainer handoff)
• No secrets or private history in commits

Thanks for considering the invite. If there's a preferred process (invite vs. alternate contribution path), please point me at it.

Thanks for the scoped list and for following CONTRIBUTING.md. Collaborator access needs a separate maintainer decision; this reply does not grant access or change the contribution policy.

I'm taking #143 through a maintainer documentation task, with the existing contributor proposal credited. For #149, the current thread is waiting on a host-level reproduction so we can validate file creation without weakening workspace containment. Please keep any additional findings or proposed changes linked to their corresponding issues so we can avoid duplicate work.
