fix: pass explicit argv to CLI entrypoint

[seonghobae]

Why

The LineageWeave bootstrap had to replace sys.argv before importing the CLI entrypoint. That is a monkey patch and makes the authenticated server invocation implicit.

Change

• add an optional argv parameter to contextual_orchestrator.__main__.main
• preserve normal console invocation and subcommands
• route argparse through the supplied argument list
• cover explicit argv and assert that process argv is unchanged

This PR is stacked on #765 because that is the current upstream base carrying the orchestrator auto-discovery and bounded multimodal body options consumed by LineageWeave.

Verification

• uv run --with pytest pytest tests/test_cli_auth.py -q
• 9 passed

Exact-head reconciliation (2026-08-21)

• Restacked on parent refactor: publish gateway-only paper-grounded reasoning contract #765 head 39072a654261c3570496849bb4da1e2c340e2fbc; current head eb9ec5f4e3f8ecbcf96cb132f58a212981ff0a6d.
• Preserves the parent contract that an unspecified sampling temperature remains absent, so provider-default-only models do not receive an implicit 0.2.
• Focused: .venv/bin/python -m pytest -q tests/test_cli_auth.py tests/test_discover_models_cli.py — 15 passed.
• Full: .venv/bin/python -m pytest tests -q — 1521 passed in 555.46s.
• git diff --check and codegraph status passed.

✅ Devin Review: No Issues Found

Devin Review analyzed this PR and found no bugs or issues to report.

[seonghobae]

Exact-head review completed at 1ed5148. This is the clean two-file CLI boundary stacked directly on the current #765 HEAD a4e4f68; no #789 drift is included. Local proof: 9 tests passed in tests/test_cli_auth.py, Ruff, compileall, and git diff --check passed. Auto-merge is being armed; protected Checks and independent approval remain required.

[seonghobae]

Current-head verification for 1ed5148 (base a4e4f68): explicit CLI argv parsing preserves process argv and the inbound framing contracts pass locally (29 passed); Ruff, compileall, and diff --check pass. Hosted Checks and protected review remain authoritative for merge.

Exact-head RCA: Strix run 32436050151 / job 96637367737 materialized only one changed Python file, so unchanged local imports in contextual_orchestrator/main.py were absent from the temporary scan tree. The resulting ImportError report is scanner-context false positive; the current package contains those modules. The trusted central fix is stacked as ContextualWisdomLab/.github#1192 (parent #1191), which enumerates contextual_orchestrator/*.py from the exact PR head while preserving changed-file attribution. Do not weaken the Strix gate or rerun unchanged.

Exact stack recheck:

• PR head: eb9ec5f4e3f8ecbcf96cb132f58a212981ff0a6d.
• The PR records base 39072a654261c3570496849bb4da1e2c340e2fbc, but the live parent branch is 70f8b4dbb6b8d5749140581c50bcdf3b31ad8475 after subsequent normal stack merges.
• The logical fix: pass explicit argv to CLI entrypoint #801 change is already present in the live parent tree: contextual_orchestrator.__main__.main accepts explicit argv, and tests/test_cli_auth.py contains the explicit-argv regression test.
• A local merge of the live parent into the stale PR head produced no missing fix: pass explicit argv to CLI entrypoint #801 tree change; it was not pushed.

Decision: WAIT_AND_REMEDIATE as a no-op/stale-base stack item. Do not merge the stale PR head or reuse its CLEAN status as current-base evidence; the parent branch already contains the requested change.
