/**
 * Context injection — automatically inject local rules and project context
 * into agent sessions on startup.
 *
 * Sources (in priority order):
 * 1. AGENTS.md (project root)
 * 2. README.md (project root, first N chars)
 * 3. .opencode/context/*.md (project-specific context files)
 * 4. Conditional rules based on file globs
 *
 * Deduplication ensures the same content is not injected twice across
 * session rotations.
