Luis Pater 693ce1c55a feat(pluginhost, scheduler): introduce Go-based plugin with scheduler capabilities
- Added a Go scheduler plugin demonstrating CLIProxyAPI capabilities, such as `plugin.register`, `plugin.reconfigure`, and `scheduler.pick`.
- Implemented methods for plugin configuration, built-in scheduler delegation (`fill-first`, `round-robin`), dynamic candidate selection, and error handling.
- Extended `pluginhost` with scheduler handling, candidate normalization, and fallback mechanisms.
- Included examples, tests, and detailed documentation for scheduler usage and implementation.

# Standard Dynamic Library Plugin Examples
This directory contains standard dynamic library plugin examples for the CLIProxyAPI C ABI.
## Layout
- `simple/`: full provider-native skeleton that declares every supported capability.
- `model/`: model capability only.
- `auth/`: auth provider capability only.
- `frontend-auth/`: frontend auth provider capability only.
- `frontend-auth-exclusive/`: frontend auth provider that becomes the only request authentication provider when selected.
- `executor/`: executor capability only.
- `protocol-format/`: minimal executor focused on input/output format declarations.
- `request-translator/`: request translation capability only.
- `request-normalizer/`: request normalization capability only.
- `codex-service-tier/`: Go-only request normalizer that sets Codex `gpt-5.4` requests to the priority service tier when enabled.
- `scheduler/`: Go-only scheduler that can select a configured auth ID, delegate to a built-in scheduler, or deny picks.
- `response-translator/`: response translation capability only.
- `response-normalizer/`: response normalization capability only.
- `thinking/`: thinking applier capability only.
- `usage/`: usage observer capability only.
- `cli/`: command-line capability only.
- `management-api/`: Management API capability only.
- `host-callback/`: minimal Management API route that demonstrates host callbacks.
Most standard capability examples contain `go/`, `c/`, and `rust/` subdirectories. Specialized examples may provide only the implementation language they need.
## Codex Service Tier
`codex-service-tier` declares the request normalization capability. When `fast` is `true`, it sets `service_tier` to `priority` for requests where `req.ToFormat` is `codex` and `req.Model` is `gpt-5.4`.
```yaml
plugins:
configs:
codex-service-tier:
enabled: true
priority: 1
fast: false
```
## Scheduler
`scheduler` declares the scheduler capability. It can select a configured auth ID from the candidate list, delegate to the built-in `fill-first` or `round-robin` scheduler, or reject picks when `deny` is `true`.
```yaml
plugins:
configs:
scheduler:
enabled: true
priority: 1
auth_id: ""
delegate: ""
deny: false
```
`auth_id` selects a matching candidate when `delegate` is empty. `delegate` accepts `""`, `fill-first`, or `round-robin`; other non-empty values leave the pick unhandled. `deny` returns a scheduler error.
## Build All Examples
```bash
make -C examples/plugin list
make -C examples/plugin build
```
Artifacts are written to `examples/plugin/bin`.
## Notes
`protocol-format` uses a minimal executor because format declarations belong to executor capabilities.
`host-callback` uses a minimal Management API route because host callbacks are invoked from plugin methods and are not standalone capabilities.
