fix(maestro): resolve command wrappers with a shell-aware tokenizer (#199)

command_program/command_tool whitespace-split and only skipped whole
wrapper words, so quoted paths broke, sudo -u/env -i/nohup/time/npx
--yes/pnpm|yarn --silent dlx/bun x were rejected, and pnpm claude /
yarn claude (a package.json script, not `dlx claude`) resolved as a
Claude launch. Replace it with a tokenizer that honours quoting and
escaping without evaluating any expansion, and per-wrapper option
tables (env, sudo, command, nohup, time, npx, pnpm, yarn, bun) that
require dlx/x before looking through a package-manager wrapper.
Ambiguous shell grammar (pipelines, list operators, redirections,
substitution, unterminated quotes) is rejected outright rather than
guessed through; command_program still degrades to the naive first
word for display, but command_tool returns None.

Mirror the same resolver in web/src/toolIcon.ts and add
fixtures/command-resolution.json as a parity fixture both test
suites assert against.
