Add real Bottle integration

[eatdrop]

变更内容 / What changed

• 新增固定 Bottle 修复前提交和准确上游源码 Hunk 的真实第三方集成。
  Added a real third-party integration pinned to Bottle's pre-fix commit and exact upstream source hunk.
• 新增独立复现测试、边界测试、Manifest、双语案例文档和 Docker CI 作业。
  Added independent reproduction and edge-case tests, a manifest, bilingual case documentation, and a Docker CI job.
• 为固定 unittest discover Runner 增加安全的 package top-level 支持，并把 .tpl 纳入文本快照。
  Added safe package top-level support to the fixed unittest discover runner and included .tpl in text snapshots.
• 测试复制忽略标准 __pycache__ 生成物，同时继续拒绝其他非 Python 文件与符号链接。
  Test copying ignores standard __pycache__ artifacts while still rejecting other non-Python files and symbolic links.
• 版本提升至 v0.1.2，并更新 README、演示视觉和 Changelog。
  Bumped the release to v0.1.2 and updated the README, demo visual, and changelog.

原因与影响 / Why and impact

此前项目的公开证据主要来自仓库内计算器夹具和 IssueLens 前向审计，无法直接证明 PatchProof 能验证独立第三方项目的真实修复。Bottle 案例补上这项证据，并暴露出包式 unittest discovery 与模板夹具复制的通用兼容缺口。

Previously, public evidence centered on the repository-owned calculator fixture and the IssueLens forward audit, which did not directly prove validation of a real independent third-party fix. The Bottle case closes that evidence gap and exposed general compatibility needs around package-style unittest discovery and template fixtures.
