Add Process.IsRunning(int processId) static extension method

[Copilot]

Adds a static extension on Process to check whether a process with a given ID is currently running.

Changes

• ProcessExtensions.cs — new extension block on Process with a single static method IsRunning(int processId): calls GetProcessById, checks HasExited, and returns false on any exception (process not found, access denied, etc.)
• ProcessExtensionsTests.cs — tests covering a live process (Environment.ProcessId) and an already-exited process

Usage

if (Process.IsRunning(pid))
{
    // process is alive
}

Copilot was unable to run its full agentic suite in this review.

Adds a Process.IsRunning(int processId) helper intended to let callers check whether a PID refers to a currently-running process.

Changes:

• Introduces a Process extension block with IsRunning(int processId) implemented via GetProcessById + HasExited.
• Adds tests for a running PID (Environment.ProcessId) and a non-running PID (a short-lived spawned process).

A bare catch swallows all exceptions, including ones that typically should not be suppressed (and makes debugging harder if unexpected failures occur). Prefer catching the specific exceptions that represent 'not running / cannot be queried' (e.g., process not found / access denied) and let other exceptions surface, or use an exception filter to return false only for the expected cases.
