Dqwang to add the streaming pipeline and the logging system

[dqwang122]

Description

This branch contains two commits on top of main:

1. fa8c9b8 — update the streaming system

   • Adds a streaming package (env, overlap, bridges, chunk_audio, run_listen_demo) for chunked audio → ASR → debate-tree updates, watch-directory listeners, overlap/playback-driven runs, and live chunk bridges aligned with log output directories.
   • New YAML configs: base_st.yml, base_st_io.yml, overlap_debate.yml, overlap_debate_2.yml.
   • Substantial updates to ouragents.py, agents.py, debate_tree.py, tool.py, model.py, prepare.py, and related env/evaluator/search paths to integrate streaming behavior.
   • Adds analyze_streaming_performance.py and analyze_agent_timing.py for performance/timing analysis.
   • README and src/streaming/README.md document usage and CLI entrypoints.

2. d2b0e07 — update the logging system, and Pydantic

   • Introduces structured timing/logging helpers (timing_log.py) and documents them in src/scripts/README_LOGGING.md.
   • Adds llm_schemas.py (Pydantic) and wires schema-oriented flows where appropriate.
   • Dependency and small config/helper updates (requirements.txt, .gitignore, compare_env.py, DB/helper utilities).

Diff summary: ~35 files changed, +5509 / −333 lines vs origin/main.

Motivation and Context

Supports incremental / streaming debate runs (chunked speech, overlap timing, bridges from TTS or log outputs) and improves observability (timing logs) and structured LLM I/O (Pydantic), so experiments and demos can match online/chunked pipelines and be analyzed with the new scripts.

How Has This Been Tested?

• If you are adding a new feature, test on your own test scripts.

(Replace with what you actually ran—e.g. overlap/non-overlap streaming CLIs from src/streaming/README.md, and/or analyze_streaming_performance.py on a sample log.)

Screenshots of Test Results (if appropriate):

1. Your own tests:

(Optional: e.g. plots from analyze_streaming_performance.py or overlap timeline PNGs under log_files/.../outputs.)
