PR Summary

Medium Risk
Changes how PTY sessions start (user, env, cwd) and adds URL-driven launch flows; mistakes could affect sandbox execution context, though confirmation gates untrusted links.

Overview
Adds configurable PTY launch options (user, cwd, env) for dashboard terminals instead of a fixed working directory.

Terminal routes and /dashboard?tab=terminal now accept user, cwd, and repeated env query params. Values are parsed into TerminalPtyOptions and passed into DashboardTerminal; links that include PTY params trigger a confirmation dialog (alongside URL commands) where users can review cwd and edit user/env before starting.

Sandbox-scoped terminal views enable allowPtySettings: a header settings control opens a PTY dialog, optional “Make default” persistence via per-user cookies, and apply triggers reconnect. Team terminal sign-in return URLs preserve the new query params.

PTY creation uses normalized options from stored defaults, URL (when not confirmation-gated), or confirmed launch settings. resolveBrowserSandboxUrl rewrites envd sandboxUrl in the browser to the 49983-{sandboxId}. host prefix for client-proxy routing.

Unit tests cover PTY parsing, cookie round-trip, URL rewriting, and the removal of hardcoded /home/user cwd.
