Add Import AST node, Call.module, and Module.imports. parse_module accepts `import foo` before any def/type; parse_atom_postfix reads `mod.func(...)` into Call(module="mod"). `as`/`from` forms error for now. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
load_program parses the entry module and every transitively imported module from the entry directory. Detects missing modules, import cycles, and main defined in an imported module. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Process the whole LoadedProgram: collect signatures across all modules keyed by (module, name), enforce main only on the entry module, and resolve qualified calls (mod.func) against imported modules. Record each call's resolved target in call_resolution for irgen. Add analyze_program; analyze() now wraps a single module in a LoadedProgram.

irgen emits every module's functions, qualifying imported symbols as
rw_user_<module>_<name> and resolving calls/spawns via call_resolution.
driver routes compile/emit-ir/emit-ast through load_program +
analyze_program. Add examples/import_basic{,_lib}.rw and e2e coverage.

概要
rw を単一ファイルから複数ファイルへ拡張する、Python 風 import の PR1 / 全3 PR。
import fooで同一ディレクトリのfoo.rwを取り込み、foo.bar()と修飾して呼べるようにする。名前空間付き import の全インフラ（DOT トークン・ローダ・名前空間付き関数テーブル・irgen シンボル規約・循環検出）を本 PR に集約する。import math_lib→math_lib.add(2, 3)と修飾呼び出しmain定義もエラーrw_user_<module>_<name>シンボル）from x import y（PR2）とimport x as m（PR3）は後続。設計はdocs/specs/17-namespaced-imports.mdに 3 PR 分まとめてある。設計の要点
Call.module: Optional[str]=Noneを足し、修飾呼び出しだけを区別。デフォルト None なので既存のCall生成・ビルトイン分岐（callee == "print"等）は無改変。member-access ノード化は却下（数十の分岐が全壊するため）。(module, name)でキー化して統合解析。main必須チェックは entry モジュールのみ。SemaResult.call_resolution: Dict[id(Call), (module, name)]で呼び出しの実体を irgen に伝える。PR2/PR3 の別名解決もここに乗る。rwc/loader.pyに隔離（driver は配線のみ）。変更ファイル
