feat: publish Judgeval JQL skill

[JJwilkin]

Summary

Publish the judgeval-jql skill for coding agents, with progressive Python and TypeScript references plus a single-fetch full.md bundle.

Source and provenance

• JudgmentLabs/jql#74 is merged.
• The published artifacts come from its merge commit: JudgmentLabs/jql@c92a144f7440814458c85c31573e2572cd95c888.
• skills/judgeval-jql/source.json records that immutable commit and the SHA-256 hash of every copied artifact.
• CI verifies all four published files against the recorded hashes.

Changes

• add the generated skills/judgeval-jql/** artifact
• publish runtime-neutral guidance with focused Python and TypeScript references
• publish full.md with one document hierarchy and in-document runtime links
• document installation and stable docs-hosted reference URLs
• bump the Claude and Cursor plugin releases to 1.1.0; the marketplace catalog version remains independent

Validation

• confirmed all four artifacts are byte-identical to the JQL #74 merge commit
• node scripts/check-jql-skill-provenance.mjs
• parsed all JSON manifests
• installed with npx skills add ... --skill judgeval-jql --agent codex --copy -y
• confirmed installed skill and provenance files remained byte-identical
• upstream JQL generator, freshness, contract, and runtime tests pass

Remaining release dependency

Do not merge this PR until JudgmentLabs/judgeval#762 is merged and its production release workflow successfully publishes judgeval==1.3.0 to PyPI. That is the first public Python release containing judgeval.jql.

After 1.3.0 is available:

1. Validate the installed Python examples against the released package.
2. Get the required approval and merge this PR.
3. Update JudgmentLabs/docs#456 to pin this PR's final publication commit and verify its preview endpoints.

The four skill files are byte-for-byte copies from JudgmentLabs/jql#74, so I left the content findings on that PR (notably: full.md opens with two H1s and instructs its reader to fetch the files it replaces; the TypeScript retry example doesn't compile to anything usable; the agg doc line drops half a validation rule). Comments here are about what's specific to this repo.
