fix(core): cap ChordMatcher buffer to prevent unbounded growth

[ionfwsrijan]

Description

ChordMatcher stores every key press in its internal buffer without a size limit. Holding down a key floods the buffer, and the chord is never matched against the expected sequence, breaking chord detection.

Changes

• Added maxBufferSize option (default 10) to the ChordMatcher constructor
• Before attempting a match, checks if buffer length exceeds the limit
• When over limit, resets the buffer, then continues to match the current key against the expected chord

Testing

• Verified unbounded key presses no longer break chord matching
• Buffer resets cleanly when limit is exceeded
• Existing chord tests continue to pass

Closes #1711

⌛ 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 refill rate.

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, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.
