Release Notes v0.2.0

# Release Notes v0.2.0 @justindevs

Package: `@jstn-sdk/rcs@0.2.0`

Tag: `v0.2.0`

Release date: `2026-05-11`

## Summary

`v0.2.0` is the first minor line after the `0.1.x` patch series: it ships reference-level integration for Cursor and MCP-capable editors while keeping Codex native setup as Tier 1. This release documents how to consume canonical `skills/` and `templates/AGENTS.md` without pretending Codex hooks, native agents, or `.rcs/` runtime semantics port one-to-one.

## Highlights

- Cursor + RCS — new [`docs/reference/cursor-rcs-integration.md`]: project rules, SSOT boundaries, optional MCP pointer.

- MCP IDE presets — new [`docs/reference/mcp-capable-ide-presets.md`]: copy-paste `mcp.json` for all first-party `rcs mcp-serve` targets (`state`, `memory`, `code-intel`, `trace`, `wiki`), aligned with `src/config/rcs-first-party-mcp.ts`.

- Platform manifest — `cursor` and `mcp-capable-ide` lanes move to `active` at the reference-doc layer; `claude-like` stays planned until a similar ship.

- README support matrix — Tier 2 now points at the shipped reference docs and clarifies `claude-like` vs Cursor/MCP.

- Corpora clarity — expanded [`corpora/README.md`]

- Compat doctor tests — cross-platform normalization for `doctor` contract fixtures (Windows short paths, `tmux.cmd` stub, `RCS_RUNTIME_BRIDGE` isolation) and onboarding fixture alignment.
