Expand execution scaffolding and clarify terminology

[franksong2702]

What changed

• add six executable textbook lab packages and an end-to-end evaluation engineering example
• add five Agent Bible capability running-rule samples, generated JSON, compiler, and semantic checker
• replace opaque terminology in current documentation with plain Chinese while preserving signed and historical snapshots
• add a terminology audit and regression checker integrated into the knowledge-base health check
• synchronize ADS generated files, navigation, governance, and repository self-description

Why

The knowledge base had strong conceptual coverage but needed more executable scaffolding and clearer reader-facing language. It also needed mechanical protection against terminology drift and generated-file divergence.

Validation

• python3 _tools/check_plain_language_terms.py
• python3 _tools/compile_decision_system.py --check
• python3 _tools/compile_agent_contracts.py --check
• python3 _tools/check_agent_contracts.py
• python3 _tools/check_ads_case_crossrefs.py
• python3 _tools/kb_health_check.py
• git diff --cached --check

All checks passed locally.

Owner review: approved for merge

Scope check: clean. The diff matches the PR description: executable teaching scaffolding, Agent Bible running rules and generated JSON, terminology cleanup, and regression tooling.

Critical review: no blocking findings. The Python tools use argument-array subprocess calls; no shell=True, eval, exec, credential material, database writes, or untrusted LLM output execution was introduced.

Independent verification:

• extracted the reference code from all six textbook labs plus the Evaluation engineering sample into temporary directories
• 30 unit tests passed across Labs 02/07/09/10/12 and the Evaluation bundle
• Lab 05 local mock pipeline passed first-run counts and second-run checkpoint/idempotency checks
• ADS compiler: 76 entries, strict validation and generated YAML sync passed
• Agent rules: 5 contracts, 50 case definitions, 5 trace samples passed
• terminology guard: 0 current-document violations
• full knowledge-base health check passed; broken/ambiguous links: 0
• GitHub Actions KB Health Check passed

No blocking review findings. Safe to merge.
