Instance service init has no timeout and can hang the bootstrap layer indefinitely

Title:
Instance service init has no timeout and can hang the bootstrap layer indefinitely

Description:
packages/opencode/src/project/bootstrap.ts calls init() on each per-instance service
(lsp, share, format, vcs, snapshot, project) inside an Effect.forEach with
concurrency: "unbounded". Each init() is unbounded; the existing catchCause only
fires on rejection, not on hang; and there is no per-service log line. When a single
service hangs (broken native binding, deadlocked internal state, slow disk that
prevents the share/format services from enumerating, etc.) the bootstrap layer
silently waits, the rest of the services may also stall depending on shared
InstanceState, and there is no log line to point at the offending service.

#33905 covered the related plugin-init npm install and was fixed in the npm install
path. The instance service bootstrap itself is a separate layer and still has no
timeout.

Plugins: n/a
OpenCode version: dev (dc4449df0d)

Steps to reproduce:

1. Replace one of the bootstrap services (e.g. format) with an implementation whose
   init() returns a never-resolving Effect.
2. Open a project directory.
3. InstanceBootstrap.run never returns. No log line identifies the hanging service.

Expected behaviour:

• The hanging service's init is interrupted within a few seconds.
• The bootstrap completes for the other services.
• A logWarning is emitted that names the service so the misbehaving one is locatable.

Actual behaviour:

• The bootstrap blocks indefinitely.
• No log line is emitted until the process is killed.

Operating System: n/a (reproducible on any platform)
Terminal: n/a

Related / duplicate check:

• #33905 (closed): same symptom class for the npm install inside the config layer.
• #37111 (open): opencode web hangs inside @parcel/watcher native subscribe; this
  issue is scoped to the bootstrap layer in project/bootstrap.ts, not the watcher.
