• Added a new CI job to automatically test reverse dependencies

[coderabbitai]

Walkthrough

The changes introduce a new CI workflow job and supporting script logic to test reverse dependencies of the project using an OPAM_DEPENDS environment variable. The main build script is refactored to modularize repository preparation and dependency testing, while the workflow files are updated to trigger these new tests and report errors as PR comments. Documentation is updated to reflect these enhancements.

Poem

🐇
In the warren of code where dependencies sprawl,
A new script hops forth to inspect them all.
With branches and switches, it tests every friend,
Reporting each burrow where errors might end.
Now CI is smarter—oh what a delight!
The rabbit approves, with a nose twitch of might.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
