Phase 0 entry point per PHASE0.md §4, §10.
Resolves the §10 config search:
--config <path> (explicit; failure if not openable, no fallback)
$AISH_CONFIG
~/.config/aish/config.lua
./config.lua
The explicit form now hard-fails instead of silently falling through to
the next candidate — caught in smoke (`--config /nonexistent` was loading
./config.lua).
Pre-pends `./?.lua;./vendor/?.lua` to package.path so `require("dkjson")`
finds vendor/dkjson.lua and project requires resolve from the repo root.
Run from the repo root; cwd-independent resolution lands later.
`--help` prints the usage block. Unrecognized arg exits 2 with a
diagnostic on stderr.
Phase 0 done-criteria (PHASE0.md §2):
✓ shell command execution with framed output
✓ :meta commands (full §5.2 set)
✓ in-memory conversation history with sliding-window eviction
✓ codebase layout matches §4 — every module name stable for Phase 1+
⏳ live AI exchange — structurally wired; live test deferred per
issue #12 (broker endpoint hostname not resolvable from noether)
