Plugin API (breaking; the plugin system is unreleased):
- Remove the runtime `contributions` interface (register-command,
register-language, register-theme). Commands, languages and themes are
declared in plugin.toml only, so everything a plugin contributes goes
through the install preview and consent. The registry drops runtime
scope, `contribute` and `dispose_runtime`; inline `definition` in
language and theme declarations is gone.
- `completion-item.kind` is a string (the 25 LSP kinds; unknown kinds show
no icon), like the other open-ended kinds.
- `lifecycle.activate` and `commands.run` return `types.error` instead of a
string. The host maps it to the matching error kind, and only `failed`
counts against the plugin: cancelling, a missing grant or an unknown
command does not. The SDK's `Plugin` returns `Result<_, Error>`; plain
messages convert to `Error::Failed`.
Runtime:
- Editor providers of several plugins are called at the same time
(`Actor::submit` + `Pending::wait`): the wait is the slowest plugin's,
not the sum, so each gets the full edit-path budget.
Versioning and tooling:
- Components are checked at install and by `openidea-plugin check` for the
plugin API they were built for; another major or a newer minor is
refused with what to do.
- Tests: the SDK's WIT matches the host's, a simulated next-minor host
links every shipped component, every host function has an SDK wrapper,
released APIs only grow (no snapshot until the first release).
- plugins/build.sh builds every checked-in component, records a source
fingerprint next to it, and `--check` fails on stale components; CI runs
it plus fmt, clippy (host and wasm) and tests for the SDK, the official
plugins and the fixtures.
- The API evolution rules and the checklist for a new host function are in
plugins/README.md; the design notes under docs/ are removed.
