fix: preserve hyperlink parameters across wrapped lines

[harbinresearcher]

Closes #297.

When wrapped output switches from one OSC 8 hyperlink to another on the same line, the second link's continuation can inherit the first link's ID and parameters. For example, two clickable labels with id=first and id=second produce a final fragment of the second label carrying id=first.

Derive continuation parameters from the active hyperlink on each line. The propagated hyperlink state already contains any generated ID, so the separate cross-line ID cache is unnecessary. Existing IDs and metadata remain with their own link; generated IDs stay stable across that link's fragments.

Add eight public wrap() regression cases covering BEL/ST terminators, existing IDs in different parameter positions, and generated IDs with/without other metadata. All eight fail against the original implementation.

Validation:

• The complete pure-Python suite on Windows 3.12 and Linux 3.9/3.15: 1,695 passed, 49 skipped (baseline: 1,687 passed, 49 skipped).
• All 337 text-wrapping tests pass. Independent automated review found no actionable issue; this is not human review.
• Linux 3.15 with the C extension built and confirmed active: 1,758 passed, 11 skipped (baseline: 1,750 passed, 11 skipped).
• Configured tox environments flake8, flake8_tests, isort_check, pydocstyle, pylint, pylint_tests, mypy, docformatter_check, docs and twine_check pass. This includes strict Sphinx and distribution metadata/README validation.
• Installed the built ABI3 wheel into an isolated target, verified the import path and active C extension, and reran all 337 text-wrapping tests successfully.

The pure-Python runs retain skips for optional downloaded Unicode fixtures and unavailable extension comparisons. Linux 3.15 uses the project's built-in fallback benchmark fixture instead of the optional Codspeed/cffi plugin, whose pinned cffi 1.17.1 has no cp315 wheel; pytest and coverage versions remain pinned. No runtime dependencies or public APIs change.
