refactor(core): simplify interrupt continuation

+Simplify interrupt continuation: the steer-scoped resume decision now lives in SessionExecution as a post-cleanup inbox check, and the run coordinator drops its continuation state machine. Wakes arriving during cancellation cleanup now restart a normal full drain, and interrupting an idle session with continue now resumes pending steering input.

-## [MCP servers](https://opencode.ai/v2/docs/mcp-servers)
-
-Configure MCP servers under `mcp.servers`. Prefer the CLI because it preserves
-unrelated configuration. Use `--global` when the user asks to set up a service
-for themselves without limiting it to the current project; omit it when they
-explicitly want project-local configuration.
-
-```sh
-opencode2 mcp add <name> --global --url <remote-url>
-opencode2 mcp list
-```
-
-Remote servers use OAuth by default. If `mcp list` reports that a server needs
-authentication, run the OAuth flow and then verify the connection:
-
-```sh
-opencode2 mcp auth <name>
-opencode2 mcp list
-```
-
-The auth command prints an authorization URL, waits for the browser redirect,
-and stores credentials outside the OpenCode configuration. Do not ask for or
-store an API key when the server supports OAuth. Use header-based credentials
-only when OAuth is unavailable or the user explicitly requires them, and use an
-environment substitution such as `{env:MCP_API_KEY}` instead of writing a
-secret into configuration.
