fix(web): keep scroll-to-end button close to composer - #10543

💭 Clarifying scope and requirements I need to ensure that the changed TS in scope excludes tests and that no Effect service is involved. It’s important to finalize everything and clarify any conflicts in the structured schema. I should summarize all clear details and consider whether a title is necessary. It seems like the system demands specific fields, so I’ll focus on confirming success for each of these requirements.

1. browse_code — Inspect the PR head changes in apps/web/src/components/ChatView.tsx and apps/web/src/components/composerFooterLayout.ts. Determine whether any changed lines create, move, refactor, or consume an Effect service or violate the supplied Effect service conventions (Effect imports, service definitions, dependency acquisition/runtime boundaries, structured errors, static-analysis suppressions, or backend behavior test requirements). Return only concrete violations on changed lines.

2. modify_pr — not performed: the agent's request was refused before it ran

3. browse_code — Confirm whether the changed production TypeScript imports or uses the Effect library, Context.Service, Layer, ManagedRuntime, Effect runners, Schema.TaggedErrorClass, Schema.is, Effect catch APIs, or diagnostic suppression directives. Answer concisely.

4. modify_pr — not performed: the agent's request was refused before it ran

5. modify_pr — All clear

6. modify_pr — not performed: the agent's request was refused before it ran
