ocaml: phase 5.1 kmp.ml baseline (5 occurrences of "abab" in haystack)
Knuth-Morris-Pratt linear-time string search:
  - kmp_table builds failure function in O(|pattern|)
  - kmp_search scans text once in O(|text|), counting matches
  - After a hit, k := t.(n-1) so overlapping matches still count

  kmp_search "abababcabababcababcc" "abab" = 5

Hits at positions 0, 2, 7, 9, 14 (overlapping at 0/2 and 7/9).

Tests: nested while-inside-for, char inequality (.<>), pat.[i]
string indexing, Array.make 0, combined string + array indexing.

140 baseline programs total.
