Adopt Agent Plugins v1 package layout

[matt-ramotar]

Summary

• Convert plugins/store to an Agent Plugins v1.0.0 package with root plugin.json (0.3.0) and remove the Claude marketplace plus .claude-plugin manifests.
• Move contributor skills from .claude/skills/ into plugins/internal/documentation as a second portable plugin (0.1.0).
• Point AGENTS.md and the store plugin README at the new paths. Claude Code /plugin marketplace add for this repo no longer applies.

Test plan

• Confirm plugins/store/plugin.json and plugins/internal/documentation/plugin.json use https://agent-plugins.org/schemas/1.0.0/plugin.schema.json and only permitted top-level fields.
• Confirm each skill is an immediate child of skills/ whose SKILL.md frontmatter name matches the directory name.
• Confirm .claude-plugin/ and .claude/skills/ are gone, and .claude/launch.json is unchanged.
• Load plugins/store in an Agent Plugins client and confirm building-a-store6-data-layer and migrating-to-store6 are discovered.
• Load plugins/internal/documentation and confirm documentation-discipline and code-documentation are discovered.

Docs sync checks wrong base branch

High Severity

The docs-sync guard always diffs against origin/main, but this workflow also runs on pull requests targeting store6. Relative to the wrong base, the guard can demand docs-sync-ack for docs the PR did not change, or miss docs it did change against store6.

CI downgrades to deprecated Node 20

Medium Severity

This commit replaces actions/checkout@v6 and actions/setup-java@v5 with the v4 actions that still run on Node 20. GitHub is removing Node 20 from hosted runners on 2026-09-16, so these jobs are headed for runner breakage shortly after merge.
