fix: narrow inline editor selection for pointer values, resolve correct write address

Browse Source 
resolvedSpanFor() now applies narrowPtrValueSpan() to trim the "// Module+offset"
symbol comment from the editable span, matching hitTestTarget(). Previously the
full value column text was selected, making the parser fail on commit (toULongLong
rejected the non-hex suffix), so pointer value saves were silently no-ops.

With the parse now succeeding, a second bug was exposed: setNodeValue() computed
write addresses via computeOffset() which sums tree offsets without dereferencing
pointers. For nodes inside expanded pointer targets (e.g. VTable entries), this
wrote to struct_base+child_offset instead of *ptr_value+child_offset, causing an
access violation crash. The fix passes lm->offsetAddr (the compose-resolved
absolute address) through the inlineEditCommitted signal so setNodeValue() uses
the correct dereferenced address.
