fix: bump aibridge to v1.0.9 to forward Anthropic-Beta header by ssncferreira · Pull Request #22936 · coder/coder

Bumps aibridge to v1.0.9, which forwards the Anthropic-Beta header from client requests to the upstream Anthropic API: coder/aibridge#205

This fixes the context_management: Extra inputs are not permitted error when using Claude Code with AI Bridge.

Note: v1.0.8 was retracted due to a conflict marker cached by the Go module proxy coder/aibridge#208. v1.0.9 contains the same fix.
