Edit prediction: add some typescript evals, fix a teacher model failure mode (#50141)
In some evals, the teacher produced hallucinations, seemingly due to
context rot. This makes the zeta prompt crate's budgeted rendering
usable by the teacher, so that it can truncate the list of excerpts.

I've also cleaned up the implementation of zeta_prompt's
`format_related_files_within_budget`, and changed the behavior so that
it filters the the excerpts by priority but renders the files in their
original order.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship
