[Archived PR] fix: upgrade DevProxy from v2.1.0 to v2.3.4 #695

Original author: Cedric Vidal (@cedricvidal)

Summary

Upgrades DevProxy sidecar from v2.1.0 to v2.3.4 across all worker deployments and config maps.

Motivation

DevProxy v2.3.4 includes dotnet/dev-proxy#1627 — "Fix HAR entry timestamp to use UTC date time" — which fixes the request timestamping issue reported in #694.

Changes

Image tags (ghcr.io/dotnet/dev-proxy:2.1.0 → 2.3.4)

• deploy/base/workers/coder-acp-claude-code.yaml
• deploy/base/workers/coder-acp-copilot.yaml
• deploy/base/workers/coder-vscode-electron-driver-ext.yaml

Config schema URLs (v2.1.0/rc.schema.json → v2.3.4/rc.schema.json)

• deploy/base/workers/devproxy-claude-code-config.yaml
• deploy/base/workers/devproxy-config.yaml
• deploy/base/workers/devproxy-vscode-electron-driver-ext-config.yaml

Version gap (v2.1.0 → v2.3.4)

No breaking changes. Notable additions in intermediate versions:

• v2.2.0: YAML config support, --output json flag, TTY detection, OpenAI Responses API support, detached mode
• v2.3.0: Multiple DevProxy instances when asSystemProxy: false, detach mode improvements
• v2.3.1–v2.3.3: Bug fixes
• v2.3.4: HAR timestamp UTC fix (the target fix)

Testing

• All 81 existing DevProxy client and HAR parser tests pass
• No code changes needed — this is a pure infrastructure version bump

Closes #694
