Hojun-Cho 48904e5ef3 lib/regex: fold-2c — findall/result_freeall
findall (regex.ha:923-960) over the memio seeker: one fixed stream
for the whole string, per-call suffix substring, absolute io.seek(SET)
past the scanner readahead after each match. The append-then-mutate
m[0] fix-up is verbatim Hare (the appended header shares m's backing);
the zero-length-match rune advancement guard (ha:946-952) carries the
infinite-loop protection. search's |success|=2 unwrap is the D13
explicit 3-arm match (ww-core #14); nomem propagates.
result_freeall (ha:1119-1124) verbatim, frees no-op (#27).

Tests port Hare's own findall table (+test.ha:719-731, the three
fold-2a-reachable rows) through run_findall_case's checks, plus field
rows pinning adjacency, the one-result overlap pick, multibyte
zero-length advancement (utf8sz step != 1), idx != bytesize, the
tail-match break, and the empty no-match slice. 989's run gets the
conventional timeout-180 wrap: a regression of the zero-length guard
would otherwise hang the gate (no-op frees, so no quick OOM exit).

/*
* 989_regex_run — execute the lib/regex @test fixture (fold-1 data
* model + fold-2a compile() + fold-2b tranche-A scaffolding) under
* the C-side `ww run` driver and assert exit 0.
*
* Sibling to 984_base64_run / 989_sha256_run (9xx is full so this
* shares the 989 prefix — the `short` name keys the binary, cf the
* 949_* / 989_sha256 precedent). regex_test.ww carries its own
* `export fn main()` that drives the data-model @test fns and signals
* which case failed via the exit code, so this file is a thin wrapper
* — no @test scanning, no synthetic main generation.
