Version bump, changelog heading and release notes for 2.9.0.
Summary by cubic
Bumps all packages to 2.9.0, updates the changelog heading, and adds the release notes for this version.
The headline change moves OpenCode's machine-written account, vault, usage, and session state out of the config folder into the state folder once no older plugin process is still using the old files; update and restart every OpenCode and Pi (including Thalamus-hosted servers) before upgrading so the move happens. Before downgrading, quit every host and run npx @cortexkit/opencode-anthropic-auth setup --restore-legacy. Also fixes the /claude menu briefly showing an unauthorized error after a plugin reload.
