Hojun-Cho ba13940b96 lib/path: #153 c3 buffer-ops — abs/isroot-widen/local/parent/split/pop/peek faithful port, table-driven @test (cstage) ...

Faithful ref/hare/path/buffer.ha port of the buffer-mutating ops. isroot
widened *buffer->(*buffer|str) (existing callers ptr-ident-widen); abs str-arm
strings.hasprefix(p,sepstr) (rides #154); local lifts Hare's `static let buf`
to a module-private [MAX]u8 index-write (no ww static-append, regex.ww:1177).

Three documented respells (never silent): split binds each (str|void) elem to
an ident before return (#22b); peek binds split() to a local (#48); local's
index-write. parent via appendnorm + frombytes.

Tests mirror Hare's pop() @test 1:1 (stack.ha:147) + table-driven
abs/isroot/local/parent rows off a local buffer. cstage-first; wwstage str-arms
ride deferred #146 (path stays M_WWREJECT). lib/path non-embedded (no
combined.ww regen). Completes the c3 stage of the path arc.
