Dotta 1ca3331c33 [codex] Fix mobile issue chat spacing (#8493)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The issue page is one of the main surfaces where operators read
agent updates and manage task relationships.
> - On narrow mobile viewports, agent chat bubbles kept the desktop
`max-w-[85%]` cap, leaving the right side overly indented.
> - The same issue sidebar can also become noisy when many blockers or
sub-tasks are attached to a task.
> - This pull request adjusts the mobile chat bubble width while
preserving the existing desktop cap.
> - It also limits long issue-relation previews until the operator
expands them, then allows collapsing them again.
> - The benefit is a denser, more readable mobile issue page without
changing the underlying issue data model.

## Linked Issues or Issue Description

No public GitHub issue exists for this internal report.

Bug report:
- On mobile issue pages, agent chat bubbles are unnecessarily narrow
because the desktop max-width applies at all breakpoints.
- Long blocked-by and sub-task relation lists can dominate the issue
properties area before the operator needs the full list.
- Related prior work: #4861 improved issue-thread scale and markdown
polish, but did not address this mobile bubble width regression.

## What Changed

- Added a responsive agent-comment bubble width class so mobile bubbles
use `max-w-[calc(100%-0.5rem)]` and desktop keeps `sm:max-w-[85%]`.
- Added test coverage for the responsive agent bubble classes.
- Added a five-item preview limit for blocked-by and sub-task relation
pills in issue properties.
- Added an inline `and N more...` / `show less` toggle for long
blocked-by and sub-task relation lists.
- Reset relation preview expansion when the `IssueProperties` panel
receives a different `issue.id`.
- Added component test coverage for collapsed, expanded, re-collapsed,
and issue-switch reset states.

## Verification

- Passed: `pnpm exec vitest run
ui/src/components/IssueProperties.test.tsx` (`27 passed`).
- Attempted: `pnpm exec vitest run
ui/src/components/IssueChatThread.test.tsx`.
- Result: failed before reaching the changed assertion because the
existing suite imports `act` from `react`, which resolves to a
non-function in this local Vitest environment.
- Scope: 50 render tests fail with `TypeError: act is not a function`; 8
non-render tests pass.
- Attempted: `pnpm --dir ui exec vitest run
src/components/IssueChatThread.test.tsx` with the same `act is not a
function` result.
- Passed: Greptile rerun reported Confidence Score 5/5 on commit
`e0f9c40b7faedcfb877d4f4b0e9f2c77a6593c16`.
- Passed: all latest-head PR checks/statuses are green, including
Typecheck + Release Registry, Build, general tests, serialized server
suites, e2e, canary dry run, policy, security review, Socket, Snyk, and
Greptile.

## Risks

Low risk:
- The chat change only alters max-width classes on agent comment bubbles
and preserves the desktop cap.
- The relation-list change is presentational; hidden blockers and
sub-tasks remain in memory and can expand/collapse in place.
- Expansion state now resets when navigating between issues in a reused
panel instance.
- Main residual risk is visual polish on real mobile devices because
local browser screenshot verification was not run in this heartbeat;
screenshots were not added because the source task explicitly requested
not adding screenshots/images unless specifically part of the work.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

OpenAI Codex coding agent based on GPT-5, with repository tool use,
shell execution, GitHub connector access, local Vitest verification,
Greptile follow-up, and PR check monitoring.
