- Remove the Kubernetes official plugin.
- `hello` and `language-toy` move from `plugins/` to
`crates/ide-plugin/tests/fixtures/`: they stay what the host's tests run
against, but are no longer listed as plugins of the repository.
- A `jobs` fixture takes over what only Kubernetes exercised: a tree view
filled by a pinned program, a terminal for the activated entry in the
invoking window, string and number settings, locally and in remote
projects.
- `plugins/` now holds only the official plugins; `build.sh`, CI and the
debug plugin catalog follow.
Adds a PR template (linked issue, what and why, how it was verified, review focus), a minimal reproduction field on the bug form and required acceptance criteria on the feature form, and CONTRIBUTING.md with the issue and PR rules. A PR check labels needs-info and leaves one comment when the issue link or the verification section is missing; it only reads the title and description.
AGENTS.md is now tracked, with CLAUDE.md linking to it, and covers layout, rules, commands, the checks CI runs, pitfalls and parallel worktrees. The verify and issue-fix skills are shared under .agents/skills and linked from .claude/skills; the rest of .claude/ stays local.
