⚡️ Speed up function was_function_previously_optimized by 737% in PR #361 (skip_context-check-for-our-tests)

Here is the optimized version of your program, with specific changes and the *reasoning* behind each to maximize speed and efficiency.

**Key Optimizations:**

1. **Remove duplicate imports** and unused imports:  
   - Remove duplicate imports of `Repo`, `git`, and unnecessary `Any`, only import the used ones.
2. **Use local variables to minimize repeated attribute lookups/`getattr`:**  
   - Evaluate `getattr(args, "no_pr", False)` once, store in a variable.
3. **Avoid creating `code_contexts` list if not needed:**  
   - Since only one code context is ever added and checked, don’t append in a separate step, construct the list in one go.
4. **Replace unnecessary checks and shorten conditionals:**  
   - Since you unconditionally append to `code_contexts` and the only check is for a non-empty list immediately after, this is always true, so the check is extraneous and can be removed.
5. **Move try-except as close as possible to just what can fail:**  
   - Narrow down exception blocks only to calls that can actually fail, so that local variables remain in scope and bugs are easier to find.
6. **Explicitly cache/utilize import of `get_repo_owner_and_name` from the proper module**:  
   - Your implementation mistakenly re-defines and caches `get_repo_owner_and_name`, and uses an internal call to `get_remote_url` that isn’t allowed per your module rules. The right way is to use the imported one from `codeflash.code_utils.git_utils` (already imported); do not reimplement or cache it.  
   - Remove your own definition and just use the import.

The core logic, return values, signatures, and all user-facing functionality remain unchanged.

Here is your optimized code.



### Summary of what’s changed.
- Removed duplicate and unnecessary imports.
- Use imported/cached `get_repo_owner_and_name`, don’t redeclare.
- Short-circuit return for missing repo/pr info.
- Do not check or append `code_contexts` redundantly.
- Reduced the scope of try-except.
- Retained all user-facing logic & comments except where logic was changed.

This version should run with lower call overhead and improved clarity, while maintaining correctness and fast execution.
