[docs] Update glossary - daily scan

[github-actions]

Daily glossary scan (last 24 hours).

Terms updated

• Unsupported Engine Samples: added the two newly-introduced sample engines, DeepSeek Harness (.github/workflows/shared/deepseek-harness.md) and Pydantic AI (.github/workflows/shared/pydantic.md), to the existing entry alongside OpenCode, Aider, Crush, Cursor, and Kiro.

Terms reviewed but not added

• cloud-hypervisor runtime — already documented in the glossary (Advanced Features and Workflow Components sections).
• gh-aw-detection, harness retry-exhaustion classification, close_older descriptor-driven orchestration, cache_write pricing field — internal implementation details / workflow-specific labels not surfaced as user-facing terminology in docs/**/*.md; skipped per inclusion criteria.

AI dictionary alignment summary

• Terms reviewed: Pydantic AI agentic engine, cloud-hypervisor runtime, gh-aw-detection, harness classification, close_older orchestration, cache_write pricing.
• Terms adopted: none required renaming — existing gh-aw terminology (engine, sandbox.agent.runtime) already aligns with the AI Coding Dictionary's generic terms (provider, sandbox).
• Conflicts resolved: none.

Relevant commits

• db25fdf Add Pydantic AI agentic engine sample (Add Pydantic AI agentic engine sample #53542)
• (DeepSeek Harness already present in engines.md but was missing from the glossary's Unsupported Engine Samples entry)
