♻️ refactor(playbook): rename agents template directory to rulesets

BREAKING CHANGE: .agents/ directory renamed to rulesets/

## Motivation

The .agents/ directory in the playbook repository caused semantic confusion:
- Playbook itself contains no source code, so it doesn't need agent rules
- .agents/ was actually a 'template library' for distribution
- This violated the principle: .agents/ = 'rules for AI in THIS project'

## Solution

Renamed .agents/ to rulesets/ to clarify its role as a template source:
- playbook repo: rulesets/ (template source)
- target projects: .agents/ (generated by sync_standards.sh, AI reads here)

## Changes

### Architecture
- Renamed: .agents/ → rulesets/
- Updated all documentation to distinguish template source vs deployment

### Scripts (all 6 scripts updated)
- sync_standards.{sh,ps1,bat}: read from rulesets/, write to .agents/
- vendor_playbook.{sh,ps1,bat}: copy rulesets/ to snapshot
- Removed backward compatibility code (clean break)

### Documentation
- README.md: updated architecture explanation
- AGENTS.md: added clarification about playbook vs target projects
- rulesets/index.md: rewritten as template library docs

### Tests
- .gitea/workflows/test.yml: updated paths
- tests/scripts/*.bats: fixed assertions (check .agents/ not rulesets/)

## Impact

### Target projects
- .agents/ path unchanged (AI still reads project root .agents/)
- Only the snapshot source path changed
- Must upgrade to new playbook version

### Migration
Users must run:
  git subtree pull --prefix docs/standards/playbook <url> main --squash
  sh docs/standards/playbook/scripts/sync_standards.sh tsl

## Verification

All tests pass (42/42):
- test_sync_standards.bats: 21/21 ✓
- test_vendor_playbook.bats: 21/21 ✓

-本仓库将规则按语言拆分为多个规则集快照：
-
-- `.agents/tsl/`：TSL 相关规则集（适用于 `.tsl`/`.tsf`）
-- `.agents/cpp/`：C++ 相关规则集（C++23，含 Modules）
-- `.agents/python/`：Python 相关规则集
-- `.agents/markdown/`：Markdown 相关规则集（仅代码格式化）
-
-目标项目落地时，通常通过 `scripts/sync_standards.*`
-将某个规则集同步到目标项目根目录的 `.agents/<lang>/`。
