windowsHide: true missing in npm-shim.js spawnSync calls — console window flashes on Windows

[luoyerr]

On Windows, when CodeGraph is running as an MCP server (launched by Claude Code), a console (cmd) window briefly flashes occasionally. This is a cosmetic issue but distracting.

Root cause

Three spawn/spawnSync calls are missing windowsHide: true:

1. npm-shim.js:48 — The main spawn that launches the bundled node.exe. Runs every time the MCP server starts or reconnects after the daemon idles out.

var res = childProcess.spawnSync(resolved.command, resolved.args, { stdio: "inherit" });

2. npm-shim.js:224 — The self-heal extraction via tar (missing platform bundle):

var res = childProcess.spawnSync("tar", args, { stdio: "ignore" });

3. src/extraction/wasm-runtime-flags.ts — The relaunchWithWasmRuntimeFlagsIfNeeded re-execs node:

const result = spawnSync(process.execPath, argv, { stdio: "inherit" });

Note: mcp/index.ts's spawnDetachedDaemon already correctly sets windowsHide: true — handled during the #411 daemon refactor but the other spawnSync sites were missed.

Environment:

• Windows 11
• @colbymchenry/codegraph v0.9.6
• Launched as MCP stdio server via Claude Code

Expected: No console window appears during background process spawning.
Actual: A black console window (conhost.exe) flashes briefly.

Fix: Add windowsHide: true to the spawnSync options object at all three locations above.

Thanks for the clear write-up and root-cause analysis — pinpointing the exact spawn sites made this easy to fix.

Fixed in #1104 (merged to main). One of the three you listed (wasm-runtime-flags.ts) had already been fixed since the v0.9.6 you were on, but the two npm-shim.js sites were still open. While in there I swept every child spawn and found two more that were missing windowsHide: true (login.ts's detached cmd /c start, and the upgrade spawn), so all of them are now hidden — no more conhost flash when the server starts or reconnects after the daemon idles out. Added a source-level guard so a future bare spawn in the shim fails CI.

This will ship in the next release. Thanks again for reporting!
