What does this PR do?

A new isolated dynamic import system was introduced to prevent static analysis from eagerly bundling app dependencies. This ensures that app components, API handlers, and related logic are only compiled and loaded on demand at runtime, while a lightweight manifest system enables fast navigation and metadata access without triggering compilation.

• Fixes #23104 (GitHub issue number)
• Fixes CAL-6255 (Linear issue number - should be visible at the bottom of the GitHub issue description)

Markdown file for more better explanation is added for the maintainers to read
