Conversation
The environment map configured via PythonRewriteRpc.builder().environment() was applied to the RPC server process but not to the pip bootstrap subprocess (bootstrapOpenrewrite) or uv subprocesses (via UvExecutor). This caused pip install and uv commands to fail behind corporate proxies with SSL inspection, since they never received SSL_CERT_FILE, PIP_CERT, or proxy configuration. - Apply environment to the pip ProcessBuilder in bootstrapOpenrewrite() - Add environment parameter to UvExecutor.run() and thread it through DependencyWorkspace, UvLockRegeneration, SetupCfgParser, and RequirementsTxtParser via explicit method/constructor parameters - In PythonRewriteRpc, pass commandEnv to parseManifest() parsers and createSetupPyMarker() so all downstream subprocess calls inherit SSL/proxy configuration - Backward-compatible overloads with empty maps for all public APIs

same comment as above. AIs tends to want to leave things for backwards compatibility, but if leaving it opens us up for bugs, better to remove aggressively.

The other one was unused so I removed it, this one is still being used.

Problem
The environment map configured via
PythonRewriteRpc.builder().environment()(containingSSL_CERT_FILE, proxy vars, etc.) was applied to the RPC server process but not to:bootstrapOpenrewrite()UvExecutor(used byDependencyWorkspace,UvLockRegeneration, etc.)This caused
pip install openrewriteand uv commands to fail behind corporate proxies with SSL inspection, because the subprocesses never receivedSSL_CERT_FILE,PIP_CERT, or proxy configuration.fixes: https://github.com/moderneinc/customer-requests/issues/1891
