What changed in this PR
Simplifies bytecode precompilation in ten Python hosted-agent Dockerfiles, following the cold-start optimization work in #1153.
Changes:
- Adds
--compile-bytecodeto frozen uv dependency installation and removes separatecompileallcommands. - Limits precompilation to dependencies, dropping standard-library/application compilation and strict application syntax checks.
- Updates cold-start and
PYTHONDONTWRITEBYTECODEguidance while leaving dependency versions, base images, and entrypoints unchanged.

Summary
Use uv's built-in
--compile-bytecodeduring frozen dependency installation across all uv-based sample Dockerfiles instead of separate manual compilation commands.PYTHONDONTWRITEBYTECODEguidance next to dependency installation. Clarify that the variable disables automatic writes on import, but Python can still read valid.pycfiles.site-packagesonly. Unlike the removed manual passes, it does not precompile the standard library or copied application code, or perform a strict application syntax check.Related: #1153.
Validation
.pycgeneration and dependency import with bytecode writes disabled in an isolated uv-managed environment.
