feat: add first-class OpenCode support (wrap, learn, mcp install) (#559)
## Summary

Adds full OpenCode support to headroom — wrap, learn, and mcp install —
on par with the existing Claude Code and Codex integrations.

## Changes

### Provider slice (`headroom/providers/opencode/`)
- **runtime.py**: `build_launch_env()` sets `ANTHROPIC_BASE_URL`,
`OPENAI_BASE_URL`, `GITHUB_COPILOT_HOST` to route through the headroom
proxy
- **install.py**: `apply_provider_scope()` patches
`~/.config/opencode/opencode.json` with `baseURL` for github-copilot,
anthropic, and openai providers

### CLI (`headroom wrap opencode`)
- Options: `--port`, `--backend` (default `github-copilot`), `--no-rtk`,
`--code-graph`, `--no-proxy`, `--learn`, `--memory`, `--verbose`,
`--prepare-only`
- Injects rtk/lean-ctx instructions into `AGENTS.md`
- Token check for `GITHUB_TOKEN` / `GITHUB_COPILOT_*` env vars

### Learn plugin (`headroom/learn/plugins/opencode.py`)
- Reads `~/.local/share/opencode/opencode.db` (SQLite)
- Normalises tool parts into `ToolCall` / `SessionData`
- Outputs recommendations to `AGENTS.md` via `CodexWriter`

### MCP registrar (`headroom/mcp_registry/opencode.py`)
- Reads/writes `~/.config/opencode/opencode.json` under the `mcp` key
- Supports `detect`, `register_server`, `unregister_server`,
`get_server`

### Registration glue
- `ToolTarget.OPENCODE` in `install/models.py`
- `opencode_config_path()` in `install/paths.py`
- Registered in `providers/install_registry.py` and
`mcp_registry/install.py`

## Test plan

- `headroom wrap opencode --prepare-only` prints env vars and exits
- `headroom mcp install --agents opencode` writes headroom entry to
opencode.json
- `headroom learn opencode` mines sessions and appends to AGENTS.md
