Make T3 Code approvable for EU companies: a T3 Connect off switch

[dinooo13]

Many EU companies can't approve T3 Code for work because T3 Connect can't be turned off. If that's you, please upvote 👍

Problem.
Our company only allows T3 Code on work machines if it sends no data to the US. We're in Germany: telemetry ends up with PostHog in the US, and T3 Connect runs through Clerk and the relay. The data itself would probably be fine, but sending it to US services means GDPR paperwork for us, so the simplest solution would be to keep both off. Telemetry is already fine: T3CODE_TELEMETRY_ENABLED=false stops product analytics and, since #14413, relay tracing, and since #16563 the desktop app reads it from the shell profile. T3 Connect has no equivalent, so official builds always ship with it available. That's what blocks us (and the same requirement is in #16883).

Proposal.
One environment variable that works like the telemetry one. With T3CODE_CONNECT_ENABLED=false:

• Connect sign-in and settings are hidden, and the Clerk sign-in code isn't loaded.
• The server doesn't link, publish agent activity, or reconnect a saved link at startup.
• Direct connections (LAN, a port, SSH, Tailscale) work as before.

What doesn't change.
Nothing, unless the variable is set: no default changes, no new settings UI, no policy system, and telemetry is untouched.

Size.
Both the server and the clients already decide whether Connect is available in one place (hasCloudPublicConfig), so this would be one small PR, well under the 500-line limit, with tests.

Would you accept this? If so, we're happy to send the PR.

I couldn't wait and implemented this already: #26967.

It does what's proposed above and nothing more. With T3CODE_CONNECT_ENABLED=false, the desktop app hides Connect sign-in and settings and doesn't load the Clerk sign-in code, and the server stops linking, publishing agent activity, and restoring a saved link at startup. The variable reads values like T3CODE_TELEMETRY_ENABLED, and LAN, SSH, and Tailscale connections keep working. It's about 160 changed lines, with tests and before/after screenshots in the PR.

If the direction or scope isn't right, I'm happy to change it or close the PR.
