test: add CLI optimize parser tests

[krish110806]

Description

Adds unit tests for the egeo optimize argparse contract (build_parser).

This is a test-only PR. It does not implement markdown frontmatter support (issue #2); the source branch name is a leftover.

Maintainer follow-up on top of the original commit: the custom-options test now uses a non-default --runtime value, and the file has a trailing newline.

Type of Change

• Tests

GEO Impact

• No GEO methodology changes

Testing

• pytest tests/test_cli.py — 2 passed locally against current egeo.cli

Checklist

• Tests assert real parser defaults and one non-default override path
• Parser-only (does not run the optimize pipeline)

Additional Notes

Canonical PR for this commit. #29 was closed as a duplicate (same SHA).

Code Review Summary

Verdict: Changes Requested (1 warning that should be fixed in the test, plus process gaps)

Thank you for the first contribution — these parser tests are a useful start. I ran them locally: 2 passed against current egeo.cli.build_parser. They are parser-only (no pipeline execution, no writes, no shell). The asserted defaults match egeo/cli.py (out_dir=geo-output, schema_type=Article, runtime=python).

Please address the items below, then we can re-review. Do not treat this as a request to implement issue #2 (markdown frontmatter); this PR is test-only.

Warning

• tests/test_cli.py — test_optimize_command_custom_options passes --runtime python, which is already the default. That assertion cannot catch a regression that ignores the flag. Use a non-default value (any string is accepted; argparse does not validate runtime names) or drop the --runtime pair from this test.

Process (needed for an auditable merge)

• Fill in the PR template: what changed, why, and that this is not the frontmatter issue. Branch fix-markdown-frontmatter does not match the diff.
• Add the missing trailing newline at EOF.

Looks good

• Happy-path defaults are real assertions, not tautologies.
• --out-dir output and --schema-type FAQPage do exercise non-default parsing.
• Scope is correctly limited to argparse.

Out of scope for this PR (maintainer follow-up)

CI today does not run pytest, and pytest is not a project dependency. That is a pre-existing repo gap. Wiring pytest tests/ into CI is welcome if you want to include it, but it is not required of this contribution.

PR #29 is the same commit (85fa56b). We will treat #28 as the canonical PR.

This asserts the default, not an override. --runtime defaults to python in egeo/cli.py (_add_optimize_parser). A parse that ignored the flag would still pass. Please pass a non-default value (e.g. --runtime other) or remove this pair from the custom-options test.

Maintainer follow-up landed on this branch:

• --runtime other now exercises a non-default override
• trailing newline added
• PR description filled

Local pytest tests/test_cli.py: 2 passed on SHA f568669.

CI on first-time forks is still action_required (workflow approval). The tests themselves are parser-only and do not change product behavior.

Approve for merge when you want it on main. I am not merging.
