feat: add extra_args provider field

Browse source 
Problem: Overriding a single flag (e.g. `-outdir=build`) required
redefining the entire `args` function, duplicating all preset defaults.

Solution: Add `extra_args` field that appends to the resolved `args`
after evaluation. Accepts a static table or a context function.
