* fix(debugger): return PrepareResult when the service prepared the venv
`prepare_dependencies()` returns `PrepareResult` on every path except the
service-prepared short-circuit, which returned the venv path as a bare `str`.
`handle_launch` reads `prepared.error` on it, so every Python session whose
script has a third-party import raised `AttributeError`, hung, and failed at
180s with `Debugpy command timeout: launch`.
The two consumers of a prepare-deps response also read a `stderr` key the CLI
does not emit; the field is `install_stderr`, and it carries the same text
`error` already wraps in a sentence, so take one rather than joining both.

* fix(debugger): keep the failing step in the launch message, drop the dead branch
Preferring the raw `install_stderr` made `_first_line` pick uv's opening
progress line, so a refused launch reported "Using Python 3.12.13 environment
at: venv" — which reads like success. `error` is the same text prefixed with the
step that failed, so it is the better of the two to condense.
The installer-diagnostics pass over a `success: true` response is unreachable:
every `success: true` site in prepare_deps.rs sets `install_stderr: None`, and
its comment claimed the opposite of what that file documents. It existed to work
around a producer that warned and returned success on a failed `uv pip install`;
that producer now returns `success: false`.
