chore: 重构 OpenCode 命令和技能文档体系

- 新增：统一的 git 命令文档（add/commit/push/pull 等）
- 新增：整合的 Gitea 技能文档（API、运行器、工作流等）
- 新增：工作流模板（Android、Go、Node.js 等）
- 移除：已弃用的旧命令脚本和发布脚本
- 改进：.gitignore 添加敏感文件保护规则
- 改进：AGENTS.md 完善了开发规范和示例

此次重组统一了命令和技能的文档结构，便于后续维护和扩展。

+## What It Does

+## Quick Start

+Use this command to synchronize your local branch with the latest remote changes.
+
+## Steps
+
+### 1. Execute Pull
+
+```bash
+git pull
+```
+
+This command will:
+- Fetch updates from remote repository
+- Automatically merge changes into current branch
+- Update your working directory
+
+### 2. Handle Conflicts (if any)
+
+If merge conflicts occur:
+- Git will mark conflicting files
+- Resolve conflicts manually
+- Stage resolved files: `git add <file>`
+- Complete merge: `git commit`
+
+Or use: `/git-status` to check conflict status
+
+### 3. Display Result
+
+Show result message:
+
+```
+✓ 拉取成功
+
+分支已更新至最新状态。
+```
+

+
+然后运行：
+git add <file>
+git commit
+
+或使用 /git-status 查看详细状态
+```
+
+## Use Cases
+
+- Sync local branch with remote updates
+- Get latest changes from team

+## Related Commands
+
+- `/git-status` - Check file changes and merge status
+- `/git-push` - Push local changes to remote

+- Pulls from tracking remote branch (usually origin/main)
