conda activate base for nameless toolchains (#56785)
Stops the `conda activate base` fallback in `PythonToolchainProvider::activation_script` for two cases: 1. A Conda toolchain whose `environment.name` is `None`. 2. A Conda toolchain whose name is `Some(...)` but `shell.try_quote` rejects it. Previously both cases pushed `conda activate base` into the activation script. With miniforge installed and no env explicitly selected, every terminal silently activated `(base)`. The user didn't pick `base`; injecting it is contamination. Both branches now log a warning and emit no activation line. Users who want `(base)` can select it as the toolchain explicitly. Two unit tests cover the new behavior: `test_conda_activation_skips_when_name_missing` (name=None) and `test_conda_activation_skips_unquotable_name` (name=Some but unquotable, exercised with an embedded NUL byte that `shlex::try_quote` rejects). The existing `test_conda_activation_script_injection` still verifies that quotable names get activated. Release Notes: - Fixed Zed silently injecting `conda activate base` into terminals when a Conda manager (miniforge/miniconda) was installed but no specific environment was selected.
