fix: increase OpenCode server startup timeout from 5s to 30s

[UtkarshUsername]

What Changed

Bumped OpenCode server startup timeout from 5s to 30s (DEFAULT_OPENCODE_SERVER_TIMEOUT_MS in opencodeRuntime.ts).

Why

OpenCode server startup time is highly variable under system load. Raw child_process.spawn benchmarks on a Windows machine showed:

Run	Time to opencode server listening
1	19.6s
2	16.9s

Under normal conditions opencode serve starts in ~5-7s, but during T3 Code startup, when git operations, port discovery, provider refresh, and diagnostics queries all compete for resources, startup routinely exceeds 15s. The previous 15s timeout still caused Timed out waiting for OpenCode server start errors.

30s provides sufficient headroom for worst-case startup without meaningfully delaying failure detection (the process will exit with an error long before 30s if something is truly broken).

Note

Low Risk
Single default constant change for startup polling only; no auth, data, or API behavior changes.

Overview
Raises the default wait for the OpenCode serve process to print opencode server listening from 5s to 30s via DEFAULT_OPENCODE_SERVER_TIMEOUT_MS in opencodeRuntime.ts. Callers can still override with timeoutMs on startOpenCodeServerProcess / connectToOpenCodeServer.

This targets false Timed out waiting for OpenCode server start failures when startup is slowed by concurrent T3 Code work (git, port discovery, provider refresh, etc.), where cold starts can exceed the old limit.

Note

Increase OpenCode server startup timeout from 5s to 30s

Raises DEFAULT_OPENCODE_SERVER_TIMEOUT_MS in opencodeRuntime.ts from 5,000ms to 30,000ms to reduce false timeout failures when waiting for the OpenCode server to begin listening.

Approvability

Verdict: Approved

Simple timeout constant increase (5s → 30s) with no logic changes. The unresolved review comment references incorrect values and appears stale. This is a low-risk configuration tweak.
