## Summary
This PR mirrors the environment variable implementation we have in uv:
efc361223c/crates/uv-static/src/env_vars.rs (L6-L7).

Environment variables
ty defines and respects the following environment variables:
TY_LOG
If set, ty will use this value as the log level for its --verbose output.
Accepts any filter compatible with the tracing_subscriber crate.
For example:
TY_LOG=uv=debugis the equivalent of-vvto the command lineTY_LOG=tracewill enable all trace-level logging.
See the tracing documentation for more.
TY_LOG_PROFILE
If set to "1" or "true", ty will enable flamegraph profiling.
This creates a tracing.folded file that can be used to generate flame graphs
for performance analysis.
TY_MAX_PARALLELISM
Specifies an upper limit for the number of tasks ty is allowed to run in parallel.
For example, how many files should be checked in parallel. This isn't the same as a thread limit. ty may spawn additional threads when necessary, e.g. to watch for file system changes or a dedicated UI thread.
Externally-defined variables
ty also reads the following externally defined environment variables:
CONDA_PREFIX
Used to detect an activated Conda environment location.
If both VIRTUAL_ENV and CONDA_PREFIX are present, VIRTUAL_ENV will be preferred.
RAYON_NUM_THREADS
Specifies an upper limit for the number of threads ty uses when performing work in parallel.
Equivalent to TY_MAX_PARALLELISM.
This is a standard Rayon environment variable.
VIRTUAL_ENV
Used to detect an activated virtual environment.
XDG_CONFIG_HOME
Path to user-level configuration directory on Unix systems.
