plugins/routing/v1.1.0

## Plugin Release: routing v1.1.0

- fix: a continuation turn, such as a tool result following a prior user message, is classified instead of skipped when no active session state is found. `BuildInputWithDisposition` now returns the populated `ComplexityInput` including `LastUserText` for trailing-continuation turns in both the chat and responses paths, and `computeComplexity` falls back to classifying that recovered text, so new or recovered sessions get a tier assignment; the skip path applies only when `LastUserText` is also empty (#7122)

### Installation

```bash
# Update your go.mod to use the new plugin version
