The detection regex matched only `name() {`. bash also accepts
`function name() {` and `function name {`, and pacman_wrapper.sh uses the
keyword form for 17 of its 30 functions — so a split of that file would have
left every one of them behind in the entry script while the tool reported
success. Silent, and exactly the kind of half-done split the verifier is
meant to catch afterwards rather than the extractor causing.
Parentheses stay mandatory in the non-keyword branch. Making them optional
everywhere also matches brace groups and control constructs, which would
sweep non-function code into the library — the opposite failure, and worse.
Nine negative tests pin that boundary.
The function name now comes from a named capture group rather than
splitting on "(", which returned "function name" for the keyword form and
would have broken both --functions selection and the verifier's name matching.
Verified against the already-split files first: cco_state.sh still yields 13
functions and leechblock_fetch.sh 3, so the completed splits are unaffected.
pacman_wrapper.sh goes from 13 detected to 31.
First tests for this script: 20 cases covering every accepted spelling,
brace matching across nested bodies, and single-line functions.
