Hojun-Cho 19aa66aa5d lib/dirs+lib/os+test: add lib/dirs (XDG paths) + os.mkdirs ...

Port Hare's lib/dirs (ref/hare/dirs/xdg.ha) — XDG base-directory
lookup with mkdir-on-demand:

  dirs.config(prog) — XDG_CONFIG_HOME/<prog>, fallback $HOME/.config/<prog>
  dirs.cache(prog)  — XDG_CACHE_HOME/<prog>,  fallback $HOME/.cache/<prog>
  dirs.data(prog)   — XDG_DATA_HOME/<prog>,   fallback $HOME/.local/share/<prog>
  dirs.state(prog)  — XDG_STATE_HOME/<prog>,  fallback $HOME/.local/state/<prog>

Static-buffer return (256B pathbuf), overwritten on the next dirs.*
call — same contract as lib/temp. Fallback triggers on unset, empty,
or non-absolute XDG var (matches Hare's path::abs check). HOME-unset
rt_aborts (matches Hare's `as str` panic on missing HOME).

os.mkdirs(path, mode) — recursive mkdir, EEXIST-silenced. Walks the
path replacing each '/' with NUL, mkdir'ing each prefix, restoring
the slash. Path bytes must be writable (documented).

Surface skips with reason notes in dirs.ww header:
  - runtime() — needs stat+getuid; defer until lib/os has them
  - XDG_CONFIG_DIRS / XDG_DATA_DIRS — not in Hare's xdg.ha
  - fmt::fatalf-on-mkdir — wired to rt_abort until {n}-placeholder
    fmt lands

Cohort coverage in lib/dirs/dirstest.ww + test/wcc/975_dirs_run.c
(mkdtemp-rooted env state): XDG-absolute / XDG-non-absolute fallback /
XDG-unset×2.
