Bump React on Rails RSC to final 19.2.0

[justin808]

Summary

• updates the tutorial starter app to react-on-rails-rsc final 19.2.0
• refreshes yarn.lock for the final package tarball
• updates README version-target references from the RC line to the current final RSC package

Rationale

The tutorial should install and document the final RSC package now that 19.2.0 has been promoted from RC.

Verification

• bin/ci passed setup, RuboCop, ESLint, ReScript, generated packs, and client/server/RSC webpack builds; the first RSpec phase failed only because the Pro node renderer was not running on 127.0.0.1:3800
• started the node renderer, then bin/conductor-exec bin/rspec passed: 48 examples
• bin/conductor-exec yarn test:client passed: 4 suites, 16 tests
• rg -n "19\\.2\\.0-rc\\.4" . returned no matches in this checkout

Summary by CodeRabbit

• Documentation
  • Updated the version compatibility matrix in the README to reflect the latest supported releases.
• Chores
  • Bumped React Server Components package versions and aligned the minimum supported React version accordingly.

Reviewed this PR (code quality, correctness, security, performance).

This is a clean, minimal version bump with no issues found:

• package.json / yarn.lock changes are internally consistent — the react-on-rails-rsc entry moves cleanly from 19.2.0-rc.4 to the final 19.2.0, with a fresh resolved URL/integrity hash.
• The README "Version Targets" table update also corrects previously stale values (react_on_rails_pro/-node-renderer/react version) to match what's actually pinned in Gemfile/Gemfile.lock/package.json — verified these all agree.
• Confirmed no leftover references to the old 19.2.0-rc.4 / 17.0.0.rc.3 versions remain anywhere in the repo.
• No security or performance implications — this is a docs + dependency version alignment change only.

No changes requested. LGTM.

Reviewed. This is a clean, minimal dependency bump:

• package.json / yarn.lock consistently updated for react-on-rails-rsc 19.2.0-rc.4 → 19.2.0 (integrity hash and resolved URL updated together, no stale entries left).
• README version-target table now matches the actual values already in package.json/Gemfile.lock (react-on-rails-pro/node-renderer at 17.0.0-rc.6, react/react-dom at ~19.2.7) — this looks like it also fixes a previously-stale doc (README said rc.3 while the lockfiles were already on rc.6).
• No source/logic changes, so risk is low. Verified no remaining references to 19.2.0-rc.4 or the old rc.3 version strings anywhere in the repo.

No bugs, security, or performance concerns — LGTM.
