Force-reinstall maturin in portable top_of_tree dynamo source build

[Ankur-singh]

Problem

The portable (non-SGLang) branch of the top_of_tree dynamo source install guarded maturin behind command -v maturin and ran a plain pip install:

if ! command -v maturin &> /dev/null; then pip install --break-system-packages maturin; fi

On images that ship the maturin Python module without a console script, the guard trips (command -v maturin fails) but pip reports "already satisfied" — so no binary is created and the later maturin build dies with maturin: command not found. The hash and SGLang paths already avoid this with --force-reinstall; the portable branch was the only one missing it.

Changes

• schema.py — portable branch now force-reinstalls maturin unconditionally, matching the other two source-install paths:

  pip install --break-system-packages --force-reinstall --quiet maturin

• test_configs.py — branch-pinned assertions so the same regression is caught on all three paths (hash, top_of_tree sglang, top_of_tree portable).

Before / After

Generated top_of_tree portable branch:

- if ! command -v maturin &> /dev/null; then pip install --break-system-packages maturin; fi; fi &&
+ ...; fi &&
+ pip install --break-system-packages --force-reinstall --quiet maturin &&

bash -n confirms the generated command still parses cleanly.

Tests

The new portable assertion fails on the old code (proving it catches the bug) and passes after the fix:

# fix reverted:
tests/test_configs.py:255: assert "--force-reinstall --quiet maturin" in portable_branch  -> FAILED

Full suite with this PR — no tests broken:

705 passed, 2 skipped in make check

Note: one unrelated, pre-existing failure (test_mcp_spec.py::test_explain_field_resolves_nested_reporting_endpoint, a Union vs UnionType string-repr quirk under local Python 3.14) is present on main independent of this change.
