Phase 0 minimal output formatting per PHASE0.md skeleton.
M.assistant(text) — line-by-line; `CMD: ` lines bold+cyan
M.exec_output(output, code) — top/bottom rules; exit code on closing
rule (red on non-zero)
M.status(line) — dim "[aish] ..." single-liner
ANSI table is local to the module (no external dep). Trailing-sentinel
pattern ((text..\"\\n\"):gmatch(\"([^\\n]*)\\n\")) preserves blank lines
in assistant output rather than squashing them, at the cost of one
extra trailing newline — acceptable for Phase 0. Real syntax-aware
formatting (tree-sitter) lands in Phase 6.
Smoke verifies escape codes are emitted (od -c shows \\033[1m\\033[36m
around CMD: line) and the visual layout looks right.
