Subject: [PATCH] fix(ant-dev): dispatcher swift no-skip + lua LUA_PATH wrap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two unrelated dispatcher bugs surfaced when running the full
`ant dev example data -l <lang>` sweep across all 15 SDKs on Linux.

## swift

The adapter shipped with `skip_reason="REST/gRPC SDK is macOS-only per
antd-swift README"`, so swift was silently auto-skipped on every run.
The README claim is outdated — the swift toolchain on Linux (swift.org
release, 6.0.x) builds and round-trips against antd end-to-end. Replace
the skip with a real adapter that runs `swift run AntdExamples N`,
mirroring the csharp/kotlin number-arg pattern.

## lua

`luarocks --local --lua-version=5.4 make` installs the rock under
`~/.luarocks/share/lua/5.4/antd/`, which `lua5.4` doesn't pick up by
default. The adapter just called `lua5.4 examples/02-data.lua`, so the
example fataled with `module 'antd' not found`. Wrap the run via
`bash -c 'eval "$(luarocks --local --lua-version=5.4 path)" && exec
lua5.4 "examples/$1"'` so the freshly-installed rock is on
LUA_PATH/LUA_CPATH for the subprocess.

Filename comes from the `examples` dict (static), passed as a positional
arg to the inner shell — no string interpolation into the command line.

## Test plan

Verified end-to-end on a Linux dev box (Ubuntu 24.04, Swift 6.0.3,
Lua 5.4):

- [x] `ant dev example data -l swift` — round-trip OK, real
      `Estimate: 24 bytes in 3 chunks, ...` (no skip)
- [x] `ant dev example data -l lua` — round-trip OK
      ("Public data round-trip OK!")
- [x] Other 13 SDKs unchanged (cpp/csharp/dart/elixir/go/java/js/
      kotlin/php/python/ruby/rust/zig) — full sweep 15/15 green
