Add 5 data-research-knowledge plugins (PerryLink dsh-* family)

[PerryLink]

Plugin submission checklist

• This is a DeepSeek Harness plugin or has documented DeepSeek Harness integration.
• I used the canonical public project URL.
• I added concise English and Simplified Chinese descriptions.
• I chose an existing category, or explained why a new bilingual category is necessary.
• I ran python scripts/generate_readmes.py --check successfully.

Notes

Adds five DeepSeek Harness plugins to the data-research-knowledge category
(English README rows, bilingual catalog metadata, and the regenerated Simplified
Chinese mirror):

• Data Quality — deterministic data profiling, cleaning, and verification with a DAMA scorecard
• Fund Research — fund analysis with returns, holdings, and performance decomposition
• Industry Research — structured company/industry research with source capture and auditable trails
• Library — local document knowledge base with hybrid search and citation-aware injection
• Research Report — evidence-linked research reports with content-hash-sealed sources

All entries use canonical public URLs, concise bilingual descriptions, and the
existing data-research-knowledge category. python scripts/generate_readmes.py
and --check both pass; docs/README.zh-CN.md was regenerated from the same
catalog data.
