Add incremental analysis support for CI/CD

[sanket-deepsource]

Globstar performs a full analysis on every run, which can be time-consuming in CI/CD pipelines, and shows all issues every time. We need to implement incremental analysis that only processes changed files and their dependencies. This will significantly improve CI performance while showing only the relevant issues raised in the changes.

Requirements:

• Git integration for detecting changed files
• Dependency graph analysis for identifying affected files
• CI-specific configuration options

I was trying my hand at this issue.
For the Dependency Graph analysis, is the dependency graph to be made for the entire codebase, and then analyzing only the dependencies of the changed file? Or some other optimized approach is expected?
And is using tree-sitter the right way to extract dependencies of files?
