userland: search and exec tools, spawn library (T14)

rg (ripgrep 15.2), grep (ours, on ripgrep's regex crates), find and xargs (ours), sed (uutils 0.3 wrapper), diff and cmp (uutils diffutils 0.6 with -r), fd 10.5, jaq 2.3, env and timeout. userland/spawn is a small Command-like client of the process interface. search-test.nu: 42 cases match native tools.
