feat: add eu-legal and fi-startup-legal external plugins (Silly Pilot Oy)

[Velvoite]

Summary

• Adds external_plugins/eu-legal — 28-skill EU legal operations plugin for regulated financial institutions (GDPR/privacy, AI Act, DORA/MiCA compliance, commercial contracts, employment, regulatory intelligence)
• Adds external_plugins/fi-startup-legal — 15-skill Finnish startup legal toolkit (OY incorporation, founder agreements, ESOP/TVL §66, SHA review, BF grant compliance, first hires)
• Adds both plugins to marketplace.json

About the plugins

Both plugins are built and maintained by Silly Pilot Oy (velvoite.eu).

They connect to the Velvoite MCP server which provides live access to:

• EUR-Lex (EU legislation via CELLAR SPARQL)
• Finlex (Finnish statutes — TSL, OYL, TVL, LSL, etc.)
• PRH (Finnish company register)
• CJEU case law (via CELLAR SPARQL)
• KHO decisions (Finnish Supreme Administrative Court)
• Velvoite corpus (AI-classified EU finreg obligations, deadlines, enforcement decisions)

Core skills work without a Velvoite API key. The key unlocks corpus-backed depth. Free 30-day trial at velvoite.eu.

Both plugins are Apache 2.0.

Standalone install:

This is a refresh of two earlier submissions (#79 eu-legal, #83 fi-startup-legal) which have been open since late May with no review. Closing those in favour of this combined PR.

What's new since the earlier submissions:

• Both plugins now wire 4 new Velvoite MCP tools: search_cjeu_cases, get_eurlex_document, get_kho_decision, search_kho_decisions — giving Claude live CJEU case law and Finnish Supreme Administrative Court precedents
• Several accuracy and QA fixes across skills
• Cleaner PR description

CLA was signed on both earlier PRs and is included in the body of this one.

The CLA Assistant check on this PR was failing because it opened under the Velvoite account while the commits were authored under mattipuh (both mine — same person, different local git config at the time). Added Velvoite as co-author on a follow-up commit so the identity check can verify it, and rebased onto current main (was 6 weeks stale). Check is green and the PR is mergeable — happy to make any changes if it'd help review.
