Fix: Always disable Jest globalSetup/globalTeardown for Codeflash tests

Browse source 
## Problem
When test files were inside the project root (common case), Codeflash did NOT
create the runtime config that disables globalSetup/globalTeardown. This caused
Jest to use the project's original config WITH globalSetup, leading to failures
when globalSetup required unavailable infrastructure (Docker, databases, etc.):

    Error: Jest: Got error running globalSetup - /workspace/target/globalSetup.ts,
    reason: Command failed: docker context ls --format json
    /bin/sh: 1: docker: not found

## Root Cause
Runtime config was only created when tests were OUTSIDE project root:

    if any(not Path(d).is_relative_to(resolved_root) for d in test_dirs):
        jest_config = _create_runtime_jest_config(...)

But globalSetup should be disabled for ALL Codeflash test runs.

## Solution
Always create runtime config when `jest_config` and `test_files` exist:

    if test_files and jest_config:
        test_dirs = {str(Path(f).resolve().parent) for f in test_files}
        jest_config = _create_runtime_jest_config(jest_config, effective_cwd, test_dirs)

## Impact
- Affected: ALL projects with globalSetup/globalTeardown in Jest config
- Reproducibility: 100% systematic
- Example trace: 04dc4dcf-ca9f-449e-aed5-7a82f28c5e23

## Changes
- test_runner.py: Updated 3 functions (behavioral, benchmarking, line profiling)
- New test file: test_globalsetup_invocation_bug.py (3 test cases)
- All existing tests still pass

Fixes #18

Test for Issue #18: globalSetup not disabled when tests are inside project root.
When test files are inside the project root (common case), the runtime config that
disables globalSetup/globalTeardown is never created. This causes Jest to use the
project's original config, which may have globalSetup hooks that require
infrastructure (Docker, databases) that isn't available during Codeflash runs.
Example failure:
Error: Jest: Got error running globalSetup - /workspace/target/globalSetup.ts,
reason: Command failed: docker context ls --format json
/bin/sh: 1: docker: not found
Root cause (before fix):
In test_runner.py, _create_runtime_jest_config was only called when:
if any(not Path(d).is_relative_to(resolved_root) for d in test_dirs):
jest_config = _create_runtime_jest_config(...)
But globalSetup should be disabled for ALL Codeflash test runs, not just when
tests are outside the project root.
Fix:
Always call _create_runtime_jest_config when jest_config and test_files exist,
regardless of whether tests are inside or outside the project root.
