⚡ Bolt: Optimize patten row count deduction using vapply

[seonghobae]

Superseded by #90

This PR and #90 share the same base master@807e9405f8c32faafdf186f977a24d0b23358b43 and the same production semantic delta in R/llcont.R: replace sapply(mispatts, nrow) with vapply(mispatts, nrow, numeric(1)).

The extra generated .jules/bolt.md doctrine and source-comment wording are not independent product behavior. Canonical successor #90 intentionally restores .jules/bolt.md to the protected-base blob and retains the production delta at exact head 93824af392b7c264822ab7988f6cdf32d8fc2dcd without unsupported speedup claims.

Closing this PR is verified-successor consolidation. #90 remains Draft until fresh exact-head checks and review satisfy live policy.
