Phase 0 binding per PHASE0.md §9. M.readline(prompt) returns the line
as a Lua string (the C buffer is freed via libc free immediately after
ffi.string copies it) or nil on EOF. M.add_history skips empty lines.
Loader handles the case where libreadline-dev's unversioned
`libreadline.so` symlink isn't installed — falls through to
`readline.so.8` (current Debian/Arch ALARM) and `.so.7` (older)
before giving up. This trips on noether-the-LXD: only the runtime
package is present.
Smoke (stdin from heredoc, two lines + EOF):
p1> hello world -> "hello world"
p2> second line -> "second line"
p3> -> nil (EOF)

Smallest Phase 0 module per CLAUDE.md §4 implementation order.
M.chdir(path) returns (true) or (false, errmsg) — errmsg via
strerror(__errno_location()[0]). Glibc errno is thread-local
behind __errno_location() rather than a plain global, hence the
indirect access.
Verified against PHASE0.md §7 expectation: a libc.chdir() persists
across subsequent io.popen() calls (popen's child inherits the
parent's wd), which is the property executor.lua relies on for `cd`
interception. Smoke:
libc.chdir("/tmp"); io.popen("pwd"):read("*l") --> /tmp

- README, .gitignore, CLAUDE.md (project conventions)
- docs/PHASE0.md — full Phase 0 manifest (locked substrate)
- 10 root .lua modules + 4 ffi/ bindings, all stubs raising NotImplemented
with module-scoped responsibilities matching the manifest
- config.lua wired to current dirac/hossenfelder endpoints (qwen-coder-7b
snappy/32k + cloud via OpenRouter through hossenfelder)
File names match docs/PHASE0.md §4 exactly. Module bodies fill in across
later phases; the tree shape is locked.
