/**
 * spm_read_workspace — Local workspace file reader.
 *
 * Reads files from the user's workspace (cwd) to provide project context.
 * Two modes:
 *   - scan:  auto-discover known config/doc files and return a manifest
 *   - read:  read a specific file by relative path
 *
 * Security:
 *   - All paths resolved and validated to stay within cwd
 *   - Only .md files are allowed (no .env, .json, source code, etc.)
