vp run: add --silent option like npm/pnpm/yarn/bun/etc.

Description

Currently vp run doesn't seem to have a way to suppress the script command line and other vp diagnostic info, e.g.

$ vp run --cache check
~/cmd/admin-web$ vp check ◉ cache hit, replaying
pass: All 162 files are correctly formatted (331ms, 14 threads)
pass: Found no warnings, lint errors, or type errors in 77 files (1.4s, 14 threads)

---
vp run: cache hit, 1.96s saved.

The command line and diagnostics info is sometimes pure noise and in agentic settings only waste tokens when shown repeatedly in verification gates.

Other major JS toolchains all have --silent option in their run command, but AFAICT vp run only has --verbose adding more output, not less.

Suggested solution

Simply add a -s, --silent option like other toolchains (npm/pnpm/yarn/bun/etc.):

$ vp run --silent --cache check
pass: All 162 files are correctly formatted (331ms, 14 threads)
pass: Found no warnings, lint errors, or type errors in 77 files (1.4s, 14 threads)
