[codex] fix tile grid row sizing and rotation clearance

[thewrz]

Summary

• Keep incomplete sound-grid rows sized from the configured density columns by adding inert blank filler slots.
• Reserve rotation clearance and fit the visible tile so the current idle and hover-animated rotation stay inside each tile slot.
• Share the idle and animated rotation bounds between tile painting, hover animation, and layout.
• Add regression coverage for incomplete-row slot math, rotated tile layout bounds, very narrow slots, and rotation-bound coupling.

Root Cause

Rows were built only from real tiles, so Fill tiles stretched when the final row had fewer than the configured column count. The tile canvas also used the visible tile height as its full layout height, which left no vertical clearance for angled and hover-animated tiles.

Review / Conflict Follow-up

• Merged origin/main and resolved the sound_tile.rs conflict from the hover/playing tile feedback work.
• Idle rotation remains +/-3 degrees; hover animation reaches +/-8 degrees; tile layout now reserves for the animated bound.
• Removed the old speculative scale reserve; this branch now covers the real hover rotation animation instead.

Validation

• cargo fmt --check
• cargo test
• cargo clippy --all-targets -- -D warnings

Warning

Review limit reached

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

More reviews will be available in 29 minutes and 44 seconds. Learn how PR review limits work.

Your organization has run out of usage credits. Purchase more credits in the billing tab to continue.

⌛ 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 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 see our Fair Usage Limits Policy for further information.
