Add Rails 7 / Ruby 3.2 compatibility

[princejoseph]

Summary

• Update `rails` version constraint from `< 7.0` to `< 8.0` in all 9 gemspecs
• Update `react-rails` constraint from `< 2.5.0` to `< 3.0` (react-rails 2.7.x added Rails 7 support)
• Remove `.untaint` calls (deprecated in Ruby 2.7, removed in Ruby 3.2) from `hyperstack-config`, `hyper-state`, `hyper-trace`, and `hyper-component`
• Guard `config.assets` access in `rail_tie.rb` to support Propshaft (Rails 7 apps may not have Sprockets)
• Guard `ActiveSupport::Dependencies.require_or_load` alias in `server_side_auto_require.rb` — method removed in Rails 7.2
• Loosen `sqlite3`, `timecop`, and `rspec` dev dependency constraints to allow modern versions
• Guard `InternalMetadata.do_not_synchronize` — Rails 7.1 changed `InternalMetadata` to no longer inherit from `ActiveRecord::Base`
• Pass `**kwargs` through `has_many`/`belongs_to`/`composed_of` wrappers in `active_record_base.rb` and `permissions.rb` — Ruby 3 no longer auto-converts a trailing hash to keyword args
• Add `coder: YAML` to `serialize :data` in `queued_message.rb` — required since Rails 7.1
• Add `initializer "hyperstack.ignore_client_only_paths"` to the railtie — tells Zeitwerk to ignore `app/hyperstack/components` so component files are never autoloaded or eager-loaded server-side (fixes `NameError: uninitialized constant HyperComponent` when `eager_load = true`)
• Fix `hyperspec_compile` in `hyper-spec`: remove `.delete("\n")` — Opal 1.8.2 generates `(e = $err)\ntry{...}` for `begin/rescue` in expression position; without the newline Chrome 145 raises "Unexpected token 'try'" due to JavaScript ASI rules
• Update hyper-spec Chrome driver (`chrome_headless_github_actions`) to set `goog:loggingPrefs: { browser: 'WARNING' }` so browser console warnings/errors are captured in CI
• Update `hyper-component` test assertions for React 18 / react-rails 2.7.x behaviour changes (componentStack format, `console.error` format-string style)

CI Results (fork branch)

Since CI runs on the fork rather than this PR directly, here are the latest results:
https://github.com/princejoseph/hyperstack/actions/runs/22535687372

Gem	Result
hyper-component	✅ 294 examples, 0 failures, 26 pending
hyper-router	✅ passing
hyper-store	✅ passing
hyper-state	✅ passing
hyperstack-config	✅ passing
hyper-operation	❌ 208 examples, 56 failures, 33 pending

Pending tests: mini_racer / prerendering tests intentionally skipped

The 26 pending tests in hyper-component (and similar counts in other gems) are server-side prerendering tests tagged :prerendering_on. They require mini_racer — a native Ruby gem that embeds the V8 JavaScript engine.

mini_racer fails to compile on Ubuntu 24.04 (the current GitHub Actions runner), so it is intentionally excluded from all gemspecs. The gemspecs document this explicitly:

# spec.add_development_dependency 'mini_racer'
# fails to compile on Ubuntu 24.04; Node.js used instead; prerendering_on tests skipped in CI

When mini_racer is unavailable, spec_helper.rb skips these tests with:

skip 'mini_racer not available; skipping prerendering test'

These tests pass locally with a compatible Ruby/V8 build, and are a known CI limitation unrelated to Rails 7 compatibility.

hyper-operation failures are pre-existing

The 56 hyper-operation failures are not caused by this PR — they reproduce identically on the edge branch without any of these changes. The failures are concentrated in:

• Transport tests (transports_spec.rb): `go_ahead_and_connect` is undefined after the test patches `Hyperstack.connect` via `on_client`. This is a pre-existing test infrastructure issue unrelated to Rails version.
• Server op / uplink tests (server_op_spec.rb): depend on the transport working.
• Misc (`auto_loader_spec.rb`, `mutations_client_integration_spec.rb`): also pre-existing.

These failures exist on `edge` and are outside the scope of this Rails 7 compatibility PR.

Travis CI → GitHub Actions migration status

The project historically used Travis CI for its test matrix. Travis CI's free tier for open-source was effectively discontinued in 2021, and the `.travis.yml` now has almost all jobs commented out. Only the `hyper-operation` job remains active in Travis (running Ruby 2.6.3, EOL since April 2022), and it is superseded by the new GitHub Actions workflow.

What the Travis config originally tested

Gem	Travis status	GitHub Actions
hyperstack-config	commented out	✅ ported
hyper-state	commented out	✅ ported
hyper-component	commented out	✅ ported
hyper-router	commented out	✅ ported
hyper-store	commented out	✅ ported
hyper-operation	✅ active (Ruby 2.6.3)	✅ ported (Ruby 3.1)
hyper-model	commented out (3 jobs: part1/part2/part3, PostgreSQL)	❌ not yet ported
rails-hyperstack	commented out	❌ not yet ported
hyper-spec	commented out	❌ not yet ported
hyper-trace	commented out	❌ not yet ported (no spec dir)
hyper-i18n	commented out	❌ not yet ported (probably obsolete)

The most significant missing piece is hyper-model, which has 7 test batches (run as 3 parallel Travis jobs) and requires PostgreSQL.

Integration test app

A real Rails 7.2 app using this branch has been built, verified locally, and tested in CI:
https://github.com/princejoseph/hyperstack-test

• Installs all Hyperstack gems from this branch
• Runs `rails hyperstack:install`
• Renders a `Greetings` component with HyperModel (ActionCable real-time sync)
• System tests (Selenium + headless Chrome) pass both locally and in GitHub Actions

Test plan

• `bundle install` resolves cleanly with Rails 7.2
• `rails hyperstack:install` generator runs without errors
• Basic component renders in browser
• `bin/rails test:system` passes locally — 2 runs, 3 assertions, 0 failures, 0 errors
• System tests pass in GitHub Actions CI — https://github.com/princejoseph/hyperstack-test/actions
• hyper-component: 0 failures (was 14 before this PR's hyper-spec fixes)
• hyper-router, hyper-store, hyper-state, hyperstack-config: all passing
• 26 pending prerendering tests are a known CI limitation (mini_racer / Ubuntu 24.04 incompatibility)
• 56 hyper-operation failures confirmed pre-existing on `edge` branch

Follow-up TODOs (out of scope for this PR)

These items are identified as future work and are not blockers for merging the Rails 7 compatibility changes:

• Port `hyper-model` to GitHub Actions — add a new CI job with PostgreSQL service and run the 7 test batches (part1: batches 1–2, part2: batches 3–4, part3: batches 5–7). Travis CI is effectively dead for open-source so this is the only viable path to CI coverage for hyper-model.
• Fix `hyper-operation` transport test failures — investigate why `go_ahead_and_connect` is undefined in transports_spec.rb. The `on_client` patch of `Hyperstack.connect` appears to not propagate to the browser correctly. 56 pre-existing failures.
• Fix mini_racer prerendering tests in CI — either find a build of `mini_racer` that compiles on Ubuntu 24.04 (e.g. via a newer libv8-node gem), or use a `rubyinstaller` runner on Windows/macOS where V8 is available. 26 pending tests per gem.
• Port `rails-hyperstack` to GitHub Actions — its spec suite exercises the `hyperstack:install` generator end-to-end; currently has no CI coverage.
• Port `hyper-spec` to GitHub Actions — `hyper-spec` has its own spec suite that is currently not run in CI.
• Remove or archive `.travis.yml` — Travis CI is no longer running meaningful jobs for this project; the file only has `hyper-operation` active (on EOL Ruby 2.6.3) and is superseded by GitHub Actions.
