fix(migrated PR 4207): issue 4206 (#4279)

* Initial fix in interp_star_status function

* Removed junk lines and fixed a typo

* ci: auto fixes from pre-commit.com hooks.

for more information, see https://pre-commit.ci

* chore: adding changelog file 4279.fixed.md [dependabot-skip]

* chore: adding changelog file 4279.fixed.md [dependabot-skip]

* style: add type annotations to parameter parsing helpers in parameters.py

Add explicit type hints for math_header, array_header, is_parameter_listing,
is_math_listing, is_array_listing, and interp_star_status to improve clarity
and support static analysis.

* test: add tests for C_FullFile parameter handling in interp_star_status

Add golden "c_fullfile status" sample and multiple tests to verify
interp_star_status correctly parses C_FullFile entries. Cover mixed
SMAT/C_FullFile outputs, single C_FullFile outputs, and various
C_FullFile-like names; ensure only the "type" field is present for
C_FullFile parameters and other fields (value, MemoryMB, workspace,
shape) are not included. Also include the c_fullfile case in the
parameterized status test.
