 ### Phase 3 — proc + uplevel + upvar (THE SHOWCASE)
-- [ ] `proc name args body` — register user-defined command; args supports defaults `{name default}` and rest `args`
-- [ ] Frame stack: each proc call pushes a frame with locals dict; pop on return
-- [ ] `uplevel ?level? script` — evaluate `script` in level-N frame's env; default level is 1 (caller). `#0` is global, `#1` is relative-1
-- [ ] `upvar ?level? otherVar localVar ?…?` — alias localVar to a variable in level-N frame; reads/writes go through the alias
-- [ ] `info level`, `info level N`, `info frame`, `info vars`, `info locals`, `info globals`, `info commands`, `info procs`, `info args`, `info body`
-- [ ] `global var ?…?` — alias to global frame (sugar for `upvar #0 var var`)
-- [ ] `variable name ?value?` — namespace-scoped global
