v0.6.0 — Zero-touch activation + corporate env support

What's New

Zero-touch activation — install the VSIX, restart VS Code, done. No command-palette steps, no node server.mjs & in a terminal, no "copy this command and paste it" popups. The extension auto-installs the claude-code-cache-fix npm package (via volta install on Volta-managed systems, else npm install -g), self-spawns the proxy server as a managed child, wires ANTHROPIC_BASE_URL into the right settings shape, and cleans up on VS Code close.

Corporate environment support — works behind Zscaler / Netskope / Forcepoint / Bluecoat / custom-CA SSL inspection out of the box. Six new settings cover HTTP proxy URL, NO_PROXY, CA file path, TLS-verify toggle, and (Windows only) auto-export from the certificate store. Two new commands: Export Windows Corporate Certificates and Test Connection to Anthropic API.

Two high-severity fixes from v0.5.0:

• Proxy mode never actually engaged — claudeCode.environmentVariables is an array of {name, value} objects, but enableProxy wrote it as a flat map, so ANTHROPIC_BASE_URL was silently dropped at JSON serialization time. Now writes the correct shape while preserving existing CACHE_FIX_* entries.
• claudeCode.claudeProcessWrapper rotted on every extension update (pointed at the versioned extension folder). Now mirrors the bundled .exe to a stable per-user location and self-heals stale paths on every activate.

Volta-aware interceptor lookup — npm root -g doesn't see volta install'd packages. The extension now also checks <VOLTA_HOME>/tools/image/packages/... and tools/shared/.

NDJSON request log — ~/.claude/cache-fix-proxy-log.ndjson gets one line per /v1/messages with timestamp, model, latency, tokens, cache-read, cache-create. New command: Open Proxy Request Log. Doubles as a real cache-hit-rate signal: cacheRead / (cacheRead + cacheCreation).

New settings

Setting	Default	Purpose
autoStartProxy	true	Silently start proxy mode on activate
autoInstallInterceptor	true	Install the npm package if missing (volta/npm)
httpsProxy	""	Corporate HTTP(S) proxy URL
noProxy	localhost,127.0.0.1,::1,.local	Hosts to bypass the proxy
caFile	""	Path to PEM bundle with extra CA certificates
rejectUnauthorized	true	TLS verification (warns loudly when disabled)
autoExportCerts	false	(Windows) Auto-export from cert store
certSearchPatterns	["*Zscaler*", "*Netskope*", "*Forcepoint*"]	Subject patterns to match

Compatibility

• Requires claude-code-cache-fix@>=3.0.1 for proxy mode. The httpsProxy setting is end-to-end only on @>=3.0.3, where the upstream agent wiring lives (merged via cnighswonger/claude-code-cache-fix#54); on older versions the env vars still propagate but the proxy server ignores them.
• No regression for users without corp-env settings — with no env vars set, proxy behavior is identical to prior versions (default Node agent, system trust store).
• Tested on Windows 11 + Volta-managed Node 22.22.0 and Windows Server 2025 + plain npm. Code Insiders, stable VS Code, and Cursor all resolve the extension correctly.

Credits

Upstream proxy agent wiring (the piece that makes httpsProxy actually work end-to-end) landed in claude-code-cache-fix@3.0.3 via #54 — thanks @cnighswonger for the review and merge. The Windows pipeline-path fix in @3.0.2 also traces back to the same audit pass (#52).
