Log the effective child environment.

Lines [67-68] read from process.env, but the child receives the merged environment from Lines [70-73]. If this.opts.env overrides BROWSER or VSCODE_IPC_HOOK_CLI, the output channel reports values that the child does not receive. Build the merged environment once, use it for diagnostics, and pass the same object to cp.spawn.

Proposed fix

-    const browserEnv = process.env.BROWSER ? `BROWSER=${process.env.BROWSER}` : "BROWSER=(unset)"
-    const ipcEnv = process.env.VSCODE_IPC_HOOK_CLI ? "VSCODE_IPC_HOOK_CLI=present" : "VSCODE_IPC_HOOK_CLI=(unset)"
+    const browserEnv = env.BROWSER ? `BROWSER=${env.BROWSER}` : "BROWSER=(unset)";
+    const ipcEnv = env.VSCODE_IPC_HOOK_CLI ? "VSCODE_IPC_HOOK_CLI=present" : "VSCODE_IPC_HOOK_CLI=(unset)";

server startup flow to build the merged child environment once, using the
resulting values for the browser and IPC diagnostics instead of reading directly
from process.env. Pass that same merged environment object to cp.spawn,
preserving this.opts.env overrides.
