fix(comments): show vote counts optimistically

[tomcasaburi]

Summary

• apply the selected account's pending vote to counts returned by useComment, useComments, and useReplies
• preserve the canonical vote baseline across rapid vote transitions and stop the optimistic adjustment after a newer canonical update
• cover posts, replies, account comments, and loaded page/update stores with regression tests and documentation

Verification

• yarn build
• yarn test (1,142 passed, 6 skipped)
• manually verified in Seedit

yarn test:coverage:hooks-stores completed its test run, but the repository-wide 100% verifier reports pre-existing coverage gaps in unrelated hooks and stores.

Closes #74

Note

Medium Risk
Vote count logic spans multiple stores and rapid vote transitions; incorrect reconciliation could show wrong scores until the next update, but behavior is heavily tested and scoped to display-layer adjustments.

Overview
useComment, useComments, and useReplies now bump upvoteCount / downvoteCount as soon as the active account’s pending vote is stored, instead of waiting for the network comment to refresh.

A new optimistic-vote-counts helper records baseline and transition metadata on publishVote, reconciles counts against stale copies of the same comment in different stores, and drops the adjustment once a canonical update already reflects the latest vote. getFreshestLoadedComment picks the newest loaded comment snapshot when recording that metadata.

Docs note the behavior; hook, store, and utility tests cover rapid vote changes and reply/comment lists.

Warning

Review limit reached

@tomcasaburi, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 46 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

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 reviews.

How do review limits work?

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

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, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
