lib/strings,wcc,w6l: collapse nested-if to &&/|| at named sites (Wave-2 structural)

Browse Source 
strings.bytesub two endpoint guards, wcc cgdot/cgassign 4-deep
allptr/N_IDENT/localfindnode pyramids, and w6l isarchive's 8 sequential
magic-byte rejects. The isarchive len<8 read-guard stays a separate
statement before the || chain so the byte reads remain bounded. Not
byte-id-neutral (short-circuit emits tighter branches / renumbered
labels) but functionally identical; cs==ww stage-parity holds.
Regenerated all embedding combined.ww.
