fix(functions): include shared modules reachable via parent-escape imports

[guyofeck]

Note

Description

When a Base44 function imports a shared module that lives outside its own directory (e.g. ../../shared/response.ts), that file was previously not collected and therefore not deployed, breaking the function at runtime. This PR walks the relative-import graph starting from each function's files and includes any additional modules reachable inside the backend root, ensuring shared code is bundled and deployed alongside the functions that depend on it.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Other (please describe):

Changes Made

• Added packages/cli/src/core/resources/function/reachability.ts with collectReachableBackendFiles(), which BFS-walks relative imports (static/dynamic import, export ... from, and require) from a function's files and returns extra modules that live inside the backend root but outside the function directory.
• Resolver handles TypeScript's import-.js/ship-.ts convention, extensionless specifiers, and index.{ts,js} directory imports; imports that escape the backend root are ignored.
• Wired readFunction() and the config-less function path in readAllFunctions() (config.ts) to merge these reachable files into each function's filePaths (deduped), passing a computed backendRoot.
• Added unit tests plus a function-shared-imports fixture (two functions sharing shared/response.ts) verifying the shared file is included and that its relative path is preserved for deploy.

Testing

• I have tested these changes locally
• I have added/updated tests as needed
• All tests pass (`npm test`)

Checklist

• My code follows the project's style guidelines
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (if applicable)
• My changes generate no new warnings
• I have updated `docs/` (AGENTS.md) if I made architectural changes

Additional Notes

The traversal is confined to `backendRoot` so imports pointing outside the project are safely skipped, and results are deduped against the function's own files to avoid duplicate paths.
