The server-health module used module-level state for inProcessServerRunning,
which doesn't survive when Bun loads separate module instances in the same
process. Fix: use globalThis with Symbol.for key so the flag is truly
process-global.
- server-health.ts: replace module-level boolean with globalThis[Symbol.for()]
- export markServerRunningInProcess from tmux-utils barrel
- test: verify flag skips HTTP fetch, verify globalThis persistence
- fix(switcher): use lastIndexOf for multi-slash model IDs (e.g. aws/anthropic/claude-sonnet-4)
- fix(model-resolution): same lastIndexOf fix in doctor parseProviderModel
- fix(call-omo-agent): resolve model from agent config and forward to both
background and sync executors via DelegatedModelConfig
- fix(subagent-resolver): inherit category model/variant when agent uses
category reference without explicit model override
- test: add model override forwarding tests for call-omo-agent
- test: add multi-slash model ID test for switcher
The server health check was using /health which returns HTTP 403 since
the endpoint doesn't exist in OpenCode. The correct endpoint is
/global/health as defined in OpenCode's server routes.
Fixes#2260
