Subject: [PATCH 1/4] fix: address wrapper layer gaps - modal sandbox, DRY
 violations, double AgentOps init

- Fix modal sandbox import path from non-existent modal_sandbox.py to correct modal.py
- Prevent silent fallback to subprocess when requested sandbox type unavailable
- Deduplicate ~180 lines between run/arun methods in PraisonAI adapter
- Remove duplicate AgentOps initialization that was creating two sessions

Fixes #2094

Subject: [PATCH 2/4] fix: address critical wrapper layer issues from reviewer
 feedback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix import path from non-existent ._base to correct .base module
- Restore model resolution for dict-form llm configs (e.g. {model: 'groq/llama3-70b-8192'})
- Restore model-scoped and provider-scoped runtime resolution paths for backward compatibility
- Fix unused loop variable (task_name → _task_name) per Python conventions
- Add error handling for missing task keys with sensible defaults
- Remove unused is_available import in arun method

Subject: [PATCH 3/4] fix: add missing is_available() method to
 PraisonAIAdapter

The adapter was inheriting from FrameworkAdapter (Protocol) instead of
BaseFrameworkAdapter, causing is_available() to return None. This made
the framework appear unavailable regardless of actual installation status.

Added explicit is_available() implementation that properly checks for
praisonaiagents package availability.

Subject: [PATCH 4/4] fix: add missing resolve() method to PraisonAIAdapter

- Add resolve() method that returns self (PraisonAI has no variants)
- This fixes the AttributeError that was crashing all executions
- All other critical issues were already resolved in the rebased code
