Add make support for build and run

[Copilot]

Projects using Makefiles can't use the extension's compile/run commands because the compiler path settings always append the source file as an argument — incompatible with make. This adds a first-class make mode.

New settings

Setting	Default	Description
c-cpp-compile-run.use-make	false	Route compile/run through make instead of gcc/g++
c-cpp-compile-run.make-path	"make"	Path to make executable
c-cpp-compile-run.make-build-target	""	Build target (empty = default target)
c-cpp-compile-run.make-run-target	""	Run target (empty = execute compiled binary directly)

Changes

• package.json / configuration.ts: Four new scoped settings with corresponding accessors.
• src/make-runner.ts (new): MakeRunner class with build() and run() methods.
  • build() runs make [target] as a VS Code Task with $gcc problem matcher — no source file arg.
  • run() runs make [run-target] in the integrated terminal when a run target is configured; falls back to the normal Runner (direct binary execution) otherwise.
  • Working directory is resolved by checking for a Makefile/makefile in the source file's directory first, then falling back to the workspace root.
• compile-run-manager.ts: compile, run, and compileRun route through MakeRunner when use-make is enabled; existing gcc/g++ path is unchanged.

Example workspace config

{
  "c-cpp-compile-run.use-make": true,
  "c-cpp-compile-run.make-build-target": "all",
  "c-cpp-compile-run.make-run-target": "run"
}

This section details on the original issue you should resolve

<issue_description>Is your feature request related to a problem? Please describe.

Thank you for your extension. In some of my project I use a Makefile to determine flags and output files, and in a few cases I have a target for running the code.

Describe the solution you'd like

Please add a configuration option that calls make instead of gcc. If possible, please add the make targets for building and running the code.

Describe alternatives you've considered

Changing the executable is not enough because it would add the source file as an argument, which make does not support. Using the native vscode extensions for Makefile also don't work because I'm using this extension in code-server, which cannot use MS native extensions.
