Implements plans/01-see-introspection.md, all phases.
- see.rs: feature-free IR pretty-printer (format_ir/format_ir_with),
exhaustive over IrOp -- a new variant fails the build, not the output.
- SEE-IR <name>: post-optimization IR view with resolved callee names,
immediate/does> annotations; host-word and interpreter-token stubs.
- SEE <name>: verbatim source capture for colon words (multi-line,
comments preserved, EVALUATE-nesting safe, error-path wiped, MARKER/
REMEMBER/EMPTY roll word sources back too). Data definers (VARIABLE/
CONSTANT/CREATE/BUFFER:/2*/F*/SYNONYM) record synthesized one-liners
at definition time; VALUE/2VALUE/FVALUE/DEFER synthesize at SEE time
so current values and IS targets show. Fallback chain ends at IR dump
or host-word stub -- SEE never dead-ends on a defined word.
- HELP [<name>]: wordhelp.rs doc table with stack effect + one-line
description for EVERY word in a fresh VM (300+ dictionary words plus
all outer-interpreter tokens); a coverage test fails the build if a
word is ever added undocumented. User words echo their leading
( ... -- ... ) comment. SEE/SEE-IR prepend the HELP line as a
\ comment. Bare HELP prints usage.
- boot.fth colon definitions get real sources for free (they flow
through evaluate); INTERPRETER_TOKENS gained the missing ?DO.
524 unit + 11 compliance + 9 comparison + 5 crypto + 1 bench green;
fmt/clippy clean; core still builds --no-default-features; web
wasm-pack build unchanged.
