feat(llc): expose restrictReplies on ActivityData and FeedAddActivityRequest

[renefloor]

Summary

• Adds ActivityRestrictReplies extension type (everyone / nobody / peopleIFollow) to the domain layer
• Exposes restrictReplies on ActivityData (read model) mapped from ActivityResponseRestrictReplies
• Adds restrictReplies: AddActivityRequestRestrictReplies? to FeedAddActivityRequest so integrators can control comment restrictions when creating an activity
• Note: own_followings on FeedData was already present from the codegen in feat(llc): update openapi models #106 — no change needed there

Test plan

• melos run analyze — no issues
• flutter test in packages/stream_feeds — all 392 tests pass
• Docs snippet in docs/code_snippets/06_03_comments.dart (new restrictReplies() function) compiles cleanly

Closes FLU-356

🤖 Generated with Claude Code

Summary by CodeRabbit

• New Features
  • Added activity reply/comment restriction controls via a new restrictReplies setting (everyone, nobody, followers-only).
  • The restriction is now supported end-to-end when creating activities and is surfaced in returned activity/feed data.
• Documentation
  • Updated the changelog and added an example for posting an activity and handling restrictReplies from the resulting feed state.
• Tests
  • Added/updated unit test coverage to verify request forwarding and client-side state hydration of restrictReplies.

Warning

Review limit reached

@renefloor, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 32 minutes and 5 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

📝 Walkthrough

Walkthrough

Adds reply restriction support to activities in the Stream Feeds Flutter SDK. A new ActivityRestrictReplies extension type is introduced with everyone, nobody, peopleIFollow, and unknown values. The restrictReplies field is added to ActivityData (with response mapping) and as an optional field on FeedAddActivityRequest (propagated to the backend request). Generated Freezed code for both models is updated accordingly. Tests verify the field behavior and state hydration, a test helper is updated to support parameterized scenarios, and a usage example demonstrates the feature with a changelog entry.

Changes

Reply Restriction Support

Layer / File(s)	Summary
ActivityRestrictReplies domain type and ActivityData field packages/stream_feeds/lib/src/models/activity_data.dart, packages/stream_feeds/lib/src/models/activity_data.freezed.dart	Introduces ActivityRestrictReplies extension type with four string values (everyone, nobody, peopleIFollow, unknown) and ActivityResponseRestrictRepliesMapper.toModel(). Adds restrictReplies field to ActivityData constructor, declaration, and toModel() mapping. Updates generated Freezed code to include getter, extend equality/hashCode/toString comparisons, and wire copyWith.
FeedAddActivityRequest restrictReplies field packages/stream_feeds/lib/src/models/request/feed_add_activity_request.dart, packages/stream_feeds/lib/src/models/request/feed_add_activity_request.freezed.dart	Adds optional AddActivityRequestRestrictReplies? parameter and field to FeedAddActivityRequest, propagates it in toRequest() to the backend, and updates the generated Freezed model for equality, hashCode, toString, and copyWith.
Tests and test helper support packages/stream_feeds/test/models/activity_data_test.dart, packages/stream_feeds/test/state/feed_test.dart, packages/stream_feeds_test/lib/src/helpers/test_data.dart	Adds unit tests for FeedAddActivityRequest field behavior and verifies restrictReplies is forwarded to the backend API. Adds integration tests for getOrCreate() populating Activity.restrictReplies in feed state. Updates createDefaultActivityResponse test helper to accept optional restrictReplies parameter with everyone default.
Usage example and changelog docs/code_snippets/06_03_comments.dart, packages/stream_feeds/CHANGELOG.md	Adds restrictReplies() example function demonstrating activity creation with peopleIFollow restriction, reading back the restriction type via switch statement, and checking ownFollowings to determine commenting eligibility. Documents both new fields in the changelog.

Poem

🐇 Hop hop, who may speak today?
The rabbit checks ownFollowings array!
peopleIFollow, nobody, everyone too —
Now replies are gated, just as brand new.
The Freezed code hummed, the mapper did map,
And the bunny approved with a satisfied tap! 🎉
