Subject: [PATCH] Optimize print_version

The optimization replaces `click.echo()` with `sys.stdout.write()` for outputting the version string. The key performance improvement comes from avoiding the overhead of `click.echo()`, which includes additional formatting, color handling, and abstraction layers that aren't needed for simple text output.

**Specific changes:**
- Added `import sys` to use the standard library's direct stdout writing
- Replaced `click.echo(f"Version {together.version}")` with `sys.stdout.write(f"Version {together.version}\n")`
- Added explicit newline `\n` to maintain identical output behavior

**Why this is faster:**
`click.echo()` performs several internal operations including checking for color support, handling different output streams, and text processing. `sys.stdout.write()` bypasses all this overhead and writes directly to stdout, which is significantly faster for simple string output.

The line profiler shows the output line dropped from 1.38ms (73.6% of total time) to 0.17ms (26.2% of total time) - a ~8x improvement on that specific line, contributing to the overall 200% speedup.

**Test case performance:**
The optimization particularly benefits test cases that trigger the print functionality, such as `test_print_version_ctx_exit_called_once` (265% faster) and `test_print_version_ctx_exit_raises` (405% faster), where the reduced overhead of direct stdout writing compounds across multiple executions.
