Safety/OSV scans now launch via Popen(...).communicate() without any timeout, so a hung scanner will block the runner indefinitely and the existing TimeoutExpired handling can never fire. Prior code used a 30s timeout, which prevented the scheduler/CLI from stalling if safety wedged on network or dependency resolution. Reintroducing a timeout on the subprocess (or communicate(timeout=…)) would keep dependency scanning from hanging the entire run.
Useful? React with 👍 / 👎.

Bandit (and similarly Semgrep later in the file) now use Popen with an unbounded communicate(), so if the analyzer hangs the entire run will deadlock and the TimeoutExpired exception handler below is unreachable. Previous versions invoked these tools with a 30s timeout. Reintroducing a timeout when reading from the subprocess would prevent code analysis from hanging the runner or CI jobs on stuck tools.

Pull Request Overview
This pull request stabilizes the runner validation logic and enhances test infrastructure by resolving dependency issues and hardening error handling across scanners and workflow components.
- Adds httpx and pytest-benchmark to development dependencies for dashboard and performance testing support
- Migrates v7 enhancement features directly into ScriptRunner class, removing the separate enhancer wrapper
- Hardens script validation to properly raise FileNotFoundError/PermissionError instead of returning error dictionaries
- Adds dry-run CLI support with execution plan visualization
- Enhances task scheduler with dependency tracking and execution logging

The removal of the timeout parameter when switching from subprocess.run() to subprocess.Popen() breaks timeout functionality. The communicate() call should include a timeout parameter to prevent the scanner from hanging indefinitely if the external safety tool becomes unresponsive.
Recommended fix:
stdout, stderr = process.communicate(timeout=30)Note: The existing except subprocess.TimeoutExpired handlers at lines 231 and 337 will no longer be triggered without this timeout parameter.

| The scheduler respects dependency ordering automatically; if a prerequisite task fails, dependent tasks are skipped until the next eligible run. |

The "Benefit" line here appears to be misplaced. It describes SQLite audit trail benefits which relate to the "Compliance & Audit Logging" section above (section 10), not the Task Scheduling section. This line should either be moved up to follow line 160 (after the Compliance section code example) or removed if it's redundant.
