write-manifest <framework> ignores --force-generate #888
Description
rsconnect write-manifest <framework> --force-generate fails even though -g was passed:
$ rsconnect write-manifest api -g .
Error: The requirements file 'requirements.txt' does not exist in '.'.
Please create the file or specify a different file with --requirements-file.
To have the requirements file generated using pip freeze, pass --force-generate.
Cause
manifest_writer resolves the requirements file with force_generate and passes None (meaning "use pip freeze") to _write_framework_manifest. _write_framework_manifest then resolves it again with force_generate=False (rsconnect/main.py:4485), which turns None back into the default requirements.txt.
This affects every framework subcommand built by generate_write_manifest_python (api, flask, fastapi, dash, streamlit, bokeh, shiny, gradio, panel). write-manifest notebook -g is not affected.
Fix
Use the already-resolved value in _write_framework_manifest instead of re-resolving it, and add a test that write-manifest api -g writes a manifest and requirements.txt without an existing requirements file.
Context: the Connect docs dropped --force-generate guidance partly because of this (posit-dev/connect#46493).
