test(wiki): make the bracketed-label parity case non-vacuous (#2597)

The parity check keyed on the whole [display](target) pattern, so a link
whose display text contains brackets (Array[T] Models) never matched and the
bracket case asserted nothing. Key on the ](target) boundary instead — wiki
targets contain no ) or whitespace — so bracketed labels are actually checked.

 ## 0.9.42 (unreleased)
 
 - Fix: a cross-file INFERRED `uses` edge now binds to the symbol whose body actually references the imported name (a module-level function is a valid source; a co-located class that never touches the import gets no edge), instead of fanning out from the import line to every class in the importing file (#2652, thanks @ousamabenyounes). A reference at module top level, with no enclosing symbol, emits no edge.
+- Fix: a wiki article link now targets the article's filename verbatim instead of a percent-encoded twin, so a label with `( ) & #` or non-ASCII characters no longer produces a link that names no file on disk; the link and the on-disk filename share one canonicalization (#2597, thanks @abhay-codes07).
 - Feature: OCaml `.ml`/`.mli` extraction via tree-sitter-ocaml (optional `[ocaml]` extra). Extracts modules, top-level and module-level values/functions, types and their variant constructors, `open` imports, and function calls; qualified calls (`Geo.area`) resolve to the value, and cross-file `open`/call targets collapse onto the unique real definition via the corpus stub rewire.
 - Fix: a JS/TS `for...of` / `for...in` loop binding is now shadowed, so passing it as a call argument no longer fabricates an `indirect_call` edge to an unrelated same-named callable (#2685, thanks @ousamabenyounes); completes the loop/closure/catch shadow family (#2568/#2569/#2517).
 - Fix: graph provenance (`built_at_commit`) is stamped from the analysed repository rather than the shell's working directory, so `graphify extract` run from elsewhere records the target's commit, not the caller's (#2534 family; #2699, thanks @C0KERNEL).
