h-michaelson20 4778d61bdd Fix copy button not working for REPL error output (#40669)
## Description

Fixes the copy button functionality in REPL interactive mode error
output sections.

When executing Python code that produces errors in the REPL (e.g.,
`NameError`), the copy button in the error output section was
unresponsive. The stdout/stderr copy button worked correctly, but the
error traceback section copy button had no effect when clicked.

Fixes #40207

## Changes

Modified the following:
src/outputs.rs: Fixed context issues in render_output_controls by
replacing cx.listener() with simple closures, and added custom button
implementation for ErrorOutput that copies/opens the complete error
(name + message + traceback)
src/outputs/plain.rs: Made full_text() method public to allow access
from button handlers
src/outputs/user_error.rs: Added Clone derive to ErrorView struct and
removed a couple pieces of commented code

## Why This Matters

The copy button was clearly broken and it is useful to have for REPL
workflows. Users could potentially need to copy error messages for a
variety of reasons.

## Testing

See attached demo for proof that the fix is working as intended. (this
is my first ever commit, if there are additional test cases I need to
write or run, please let me know!)

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.
