refactor(autoFIPC): superseded by canonical distinct-count contract #324

[seonghobae]

Verified successor disposition

The only valid product delta in this PR is the autoFIPC() category-count rewrite from length(stats::na.omit(unique(x))) to sum(!is.na(unique(x))) while retaining distinct non-missing category semantics.

Canonical successor #324 at exact head e21ad17df4cea456d1f291e9e4b9eea3c6ce0062 contains that same R/aFIPC.R semantic delta, also repairs the equivalent surveyFA() path, and carries an executable equivalence contract over numeric, NA/NaN, character, factor-with-unused-level, and constant inputs. Fresh protected-base comparison for #324 is ahead-only (ahead_by=7, behind_by=0) and its effective files are only R/aFIPC.R, R/surveyFA.R, and tests/testthat/test-optimization-equivalence.R.

This PR's .jules/bolt.md addition is not a valid independent delta: it generalizes a local expression rewrite into a repository-wide performance prescription and implies performance improvement without a reproducible real/right-cleared workload benchmark. #324 deliberately does not inherit that doctrine and does not claim O(1), percentage speedup, allocation, GC, or buyer-visible latency improvement.

Accordingly #324 fully succeeds every valid semantic/test contract here while rejecting only unsupported performance doctrine. No checks, reviews, approvals, or generated performance claims from this predecessor transfer to #324. Closing unmerged as verified semantic succession, not PR-count reduction.
