fix: harden batch-2 fixes per reviewer feedback

- runner.py: isolate child process groups (start_new_session) on POSIX so
  timeout killpg cannot target the suite runner; propagate TimeoutError
  metadata + exit_code=-1 in the streaming timeout path
- agent_tools.py: route run_sync via _wrapper_bridge (C7 gate + standalone
  install hint); surface delete apply_plan failures instead of masking them;
  drop unused cwd param on acp_execute_command; B904 chaining; RUF013 Optional
- execution_mixin.py: reset _server_started[port] in finally so a failed or
  exited server can be retried by later launch() calls
- __init__.py: rebind package global db to the callable _LazyDbModule proxy so
  repeated praisonaiagents.db access returns the proxy, not the raw module
- compression_demo.py: derive target_tokens from each ratio so iterations differ
- multi-provider-agent.py: rebind each Task.agent to its RouterAgent wrapper

 - When reviewing a PR or an issue, evaluate whether the change addresses a framework concern or a user goal, and design its surface (params, naming, defaults) accordingly
 - The aim of this package is to stay **lightweight and powerful**. Do a critical review at each stage — when triaging an issue, when planning a fix, and when reviewing/implementing a PR. Reject scope creep for the sake of adding features: if a capability already exists (e.g. via existing Agent params like `instructions`/`backstory`/`tools`/`hooks`/`memory`), prefer it over a new API surface. A change must genuinely strengthen the SDK (simpler, more robust, more user-friendly) — do not add knobs, params, modules, or exports that have no live consumer or that merely duplicate existing behaviour.

-# Terminal-Bench 2.0 Integration with PraisonAI
+# Terminal-Bench 2.1 Integration with PraisonAI
 
-This directory contains examples for integrating PraisonAI Agents with **Terminal-Bench 2.0** via the **Harbor framework** for AI agent benchmarking.
+This directory contains adapters for benchmarking PraisonAI on **Terminal-Bench 2.1** via the **Harbor framework**. Everything lives in the examples/benchmark layer + CI — there are **zero changes to the `praisonaiagents` / `praisonai` SDK surface**.
 
 ## Overview
 
-[Terminal-Bench 2.0](https://tbench.ai) is a Stanford/Laude Institute benchmark that has become the gold standard for evaluating AI coding agents in real terminal environments. The [Harbor framework](https://harborframework.com) is the official evaluation harness that abstracts container lifecycle, parallelization, and cloud providers.
+[Terminal-Bench 2.1](https://www.tbench.ai/docs/run-terminal-bench-2-1) is the current release of the Laude Institute benchmark for evaluating AI coding agents in real terminal environments. The [Harbor framework](https://github.com/laude-institute/harbor) is the official evaluation harness that abstracts container lifecycle, parallelization, and cloud providers.
+
+## Setup
+
+Install Harbor and PraisonAI into **one venv** and run from the repo root with `PYTHONPATH=.` so the adapter import path resolves:
+
+```bash
+pip install harbor
+pip install -e src/praisonai-agents -e src/praisonai
+export PYTHONPATH=.
+```
 
 ## Integration Types
 
+### 0. Code Agent (headline — benchmarks `praisonai code`)
+- **File**: `praisonai_code_agent.py`
+- **Purpose**: Installs and drives the terminal-native `praisonai code` assistant headlessly inside the container.
+- **Run**:
+  ```bash
+  PYTHONPATH=. harbor run -d terminal-bench/terminal-bench-2-1 \
+    --agent "examples.terminal_bench.praisonai_code_agent:PraisonAICodeAgent" \
+    -m openai/gpt-4o-mini \
+    --ae OPENAI_API_KEY=$OPENAI_API_KEY \
+    -n 4
+  ```
+
 ### 1. External Agent (Direct Agent Class)
 - **File**: `praisonai_external_agent.py`
 - **Purpose**: External agent that uses direct `Agent()` class instantiation
-- **Usage**: Run with `--agent-import-path` flag
-- **Approach**: Uses `praisonaiagents.Agent` directly with `execute_command` tool
+- **Usage**: Run with `--agent "module:Class"`
+- **Approach**: Uses `praisonaiagents.Agent` directly with a bash tool bridged to Harbor's `exec()`
 
 ### 2. Wrapper Agent (CLI-Based)

+
+    A companion to :func:`classify_exit_reason` for the crash-loop breaker
+    referenced in Issue #3021. Where ``classify_exit_reason`` maps a *single*
+    exit to a supervisor exit code, this tracks the *rate* of restart-worthy
+    boots so a process that keeps crashing-on-resume can stop auto-resuming the
+    offending work rather than wedging in a tight restart loop.
+

+    asks whether the breaker has tripped.

+    ``window_seconds``. When tripped, the caller should stop auto-resuming the
+    offending session (while still serving real inbound) instead of restarting
+    it again immediately.
