Update CI to test Python 3.10-3.14, drop EOL versions

[Copilot]

Drop Python 3.8 and 3.9 (end-of-life) from CI test matrix, add 3.13 and 3.14. Also update setup.py to specify minimum Python version requirement.

Changes

• Test matrix: Updated to ["3.10", "3.11", "3.12", "3.13", "3.14"]
• Generate-samples and build jobs: Changed hardcoded Python 3.8 → 3.10
• setup.py: Added python_requires=">=3.10" and Python version classifiers (3.10-3.14)

 strategy:
   matrix:
-    python-version: ["3.8", "3.9", "3.10", "3.11", "3.12"]
+    python-version: ["3.10", "3.11", "3.12", "3.13", "3.14"]

 setup(
     ...
     url="https://github.com/Microsoft/cmd-call-graph",
+    python_requires=">=3.10",
     classifiers=[
         ...
+        "Programming Language :: Python :: 3",
+        "Programming Language :: Python :: 3.10",
+        "Programming Language :: Python :: 3.11",
+        "Programming Language :: Python :: 3.12",
+        "Programming Language :: Python :: 3.13",
+        "Programming Language :: Python :: 3.14",
         ...
     ]
