feat(api): nvim_set_hl{update:boolean} #37546

Browse Source 
Problem: nvim_set_hl always replaces all attributes.

Solution: Add update field. When true, merge with existing
attributes instead of replacing. Unspecified attributes are preserved.
If highlight group doesn't exist, falls back to reset mode.
