Add SenseNova-Skills to hermes-agent and openclaw

Import all 21 skills from https://github.com/OpenSenseNova/SenseNova-Skills
into both repos/hermes-agent/skills/ and repos/openclaw/skills/, so they
ship bundled with each product at install time:

- DA (3): da-excel-workflow, da-image-caption, da-large-file-analysis
- Research (6): deep-research, dimension-research, research-planning,
  research-synthesis, research-report, report-format-discovery
- Search (4+1): search-academic, search-code, search-social-cn,
  search-social-en, _search-common (shared library)
- PPT (4): ppt-entry, ppt-creative, ppt-standard, ppt-doctor
- U1 (3): u1-doctor, u1-image-base, u1-infographic

Paired with the prior commit that removed functional duplicates
(research-union, union-search-skill, research/arxiv) which the
SenseNova deep-research and search suites now cover.
