Rebase tooltip coverage (PR #2016) onto kijai/main

[laurigates]

Summary

Rebases the tooltip-coverage work behind kijai/ComfyUI-WanVideoWrapper#2016 onto the current kijai:main.

The original PR commit (docs: substantive tooltips on every INPUT_TYPES input) was based on d18cdb1. Upstream main has since advanced by 4 commits:

• 5437b01 Initial LongCatAvatar 1.5 support
• 8f1804b Fix multitalk_audio_stride init
• 1268198 Merge fix: replace 47 bare excepts with except Exception kijai/ComfyUI-WanVideoWrapper#1948 (replace 47 bare excepts with except Exception)
• 088128b Don't count .disabled as duplicate

The single tooltip commit was replayed on top of 088128b. The rebase auto-resolved with no conflicts.

Verification

9 files were touched by both upstream and the tooltip commit (MTV/nodes.py, fantasytalking/nodes.py, multitalk/nodes.py, nodes.py, nodes_model_loading.py, nodes_sampler.py, nodes_utility.py, skyreels/nodes.py, unianimate/nodes.py). I verified:

• All 29 changed .py files compile (py_compile).
• Every line upstream added in the overlap files is still present in the rebased tree (0 missing) — the bare-except fix and other upstream logic changes were preserved, not reverted.
• Net change is unchanged in scope: 29 files, 573 insertions, matching the original PR's intent.

Note

This is a draft surfacing the rebased branch. To update PR kijai#2016 itself, the rebased commit needs to land on docs/tooltips-coverage (a force-push) — happy to do that with your go-ahead.
