[Bug]: `npx t3` hangs after "Migrations ran successfully" when OpenCode provider bootstrap runs

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/server

Steps to reproduce

1. Have opencode installed and available on PATH
2. Use a normal existing ~/.t3 profile with default/empty settings
3. Run: npx t3
4. Observe startup stops after:

[18:17:08.773] INFO (#1): Running all migrations...
[18:17:08.780] INFO (#1): Migrations ran successfully
  migrations: []

5. No browser opens and no startup URL is printed

Expected behavior

T3 should continue startup, print Listening on ..., and open/pair the browser.

A provider probe failure or timeout should not block server readiness.

Actual behavior

From tracing, the startup never reaches the later readiness phases (ready.publish / browser startup). In a controlled repro, the last relevant completed provider spans before the hang were OpenCode-related (opencode.provider.list / opencode.app.agents).

Impact

Blocks work completely

Version or commit

v0.0.21. 188df6d

Environment

Linux 6.19.11-arch1-1, Node: 25.8.0, Codex: 0.123.0, OpenCode CLI: 1.14.20

Logs or stack traces

[18:17:08.773] INFO (#1): Running all migrations...
[18:17:08.780] INFO (#1): Migrations ran successfully
    migrations: []

Screenshots, recordings, or supporting files

No response

Workaround

Disable OpenCode explicitly:

  {
    "providers": {
      "opencode": {
        "enabled": false
      }
    }
  }

Additional note

t3@0.0.20 was not a viable workaround for this profile, because it failed to decode newer persisted state/caches created by newer versions.
