Dotta 87f19cd9a6 Improve issue thread scale and markdown polish (#4861)
## Thinking Path

> - Paperclip's board UI is the operator surface for supervising
AI-agent companies.
> - Issue threads are where operators read progress, respond to agents,
inspect markdown, and jump through long histories.
> - Large threads and rich markdown had become difficult to navigate and
expensive to render.
> - The previous rollup mixed these UI scale fixes with unrelated
backend recovery, costs, backups, and settings changes.
> - This pull request isolates the issue-thread scale and markdown
polish work.
> - The benefit is a reviewable UI slice that can merge independently of
the backend reliability, database backup, workflow, and board QoL PRs.

## What Changed

- Virtualized long issue chat threads and stabilized
anchor/jump-to-latest behavior for large histories.
- Added incremental issue-list row loading and tests for
scroll-triggered pagination behavior.
- Hardened markdown body rendering and markdown editor behavior around
HTML tags, image drops, code-copy UI, and escaped newline handling.
- Added a long-thread measurement harness at
`scripts/measure-issue-chat-long-thread.mjs` plus
`perf:issue-chat-long-thread`.
- Added focused UI/lib regression coverage for thread rendering,
markdown, optimistic comments, and message building.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run ui/src/components/IssueChatThread.test.tsx
ui/src/components/IssuesList.test.tsx
ui/src/components/MarkdownBody.test.tsx
ui/src/components/MarkdownEditor.test.tsx
ui/src/lib/issue-chat-messages.test.ts
ui/src/lib/optimistic-issue-comments.test.ts`
- Result: 6 test files passed, 170 tests passed.
- UI screenshots not included because this PR is covered by targeted
component tests and does not introduce a new page layout.

## Risks

- Virtualization changes can affect scroll anchoring in edge cases on
very long threads.
- Markdown/editor hardening changes are intentionally defensive, but
malformed content may render differently than before.

> 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, GPT-5.5, code execution and GitHub CLI tool use, medium
reasoning effort.
