Problem:
Test sockets live under `$TMPDIR`, which the harness points at the build
dir. On macOS/BSD `sockaddr_un.sun_path` is 104 bytes, and a CI build
path plus "nvim.<pid>.<n>" leaves little room:
/Users/runner/work/neovim/neovim/build/Xtest_tmpdir_terminal/nvim.runner/aBcDeF/nvim.12345.0
Solution:
Point XDG_RUNTIME_DIR (`stdpath('run')`) at "/tmp/nvim_<pid>". 28 bytes:
/tmp/nvim_19916/nvim.19919.1
TODO?:
- `TEMP_DIR_NAMES` prefers `$TMPDIR` over `/tmp`, so on macOS
`stdpath('run')` defaults to the long `/var/folders/<xx>/<…>/T/` path
instead of the short `/tmp` alias.
Note:
- The 104-byte limit applies to the `bind()` arg, not its "realpath",
to, so `/tmp/…` symlinks can be used to workaround the limit.

Instead of setting it in the test runner (which runs in an Nvim instance
that already has a log file), make run_tests.zig set a $NVIM_LOG_FILE
fallback path like what RunTests.cmake does.

This is in preparation of zig 0.17 where b.install_path is no
longer known inside `pub fn build()`.
Builds which should hardcode a runtime path into the binary has to specify it.
We could use a nlua0 helper to encode the install path at build time but
I think this is cleaner anyway. (like currently the appimage still
encodes a temporary build path which is nonsensical, it is better to
just include none)
Similarily b.args will not be available anymore (there will just
be an opaque pass-through)

Problem:
The Lua test harness still ran through standalone -ll mode, so tests
depended on the low-level Lua path instead of the regular Nvim Lua
environment. That also meant os.exit() coverage had to carry an ASAN
workaround because Lua's raw process exit skipped Nvim teardown and let
LeakSanitizer interfere with the observed exit code.
Solution:
Run the harness and related fixtures with nvim -l. Patch os.exit() in
the main Lua state to exit through getout(), so scripts observe normal
Nvim shutdown while standalone -ll remains available for generator-style
scripts. As a consequence, the startup test can assert os.exit() without
disabling leak detection.

Replace the busted-based Lua test runner with a repo-local harness.
The new harness runs spec files directly under `nvim -ll`, ships its own
reporter and lightweight `luassert` shim, and keeps the helper/preload
flow used by the functional and unit test suites.
Keep the file boundary model shallow and busted-like by restoring `_G`,
`package.loaded`, `package.preload`, `arg`, and the process environment
between files, without carrying extra reset APIs or custom assertion
machinery.
Update the build and test entrypoints to use the new runner, add
black-box coverage for the harness itself, and drop the bundled
busted/luacheck dependency path.
