 * Context-file and prompt-input loading for the resource loader.

 * Reads AGENTS.md / CLAUDE.md context files from the user scopes and the cwd
 * ancestor chain (warning/truncating oversized ones, since they are injected
 * into the system prompt every turn), and resolves a system-prompt input that
 * may be either an inline string or a file path. Extracted from resource-loader.ts.
 *
 * Two user scopes are read, least specific first: `~/.agents/AGENTS.md` (the
 * cross-vendor convention, so rules written for one tool are seen by hoocode)
 * and `~/.hoocode/AGENTS.md` (the native home, which therefore wins on
 * conflict). Both are additive — neither shadows the other, and no migration
 * is needed for users who already have the native file.
