runEffectFn10 bound ten curried parameters a..j but only forwarded
nine to the underlying function, silently dropping j (luacheck:
unused argument j). Forward j so all ten declared arguments reach fn.

Closes purescript-lua#1

fix: forward tenth argument in runEffectFn10

chore: normalize build tooling + luacheck-clean FFI

AGENTS.md is the single instruction file the coding agents read natively;
CLAUDE.md is a one-line @AGENTS.md import so Claude Code shares it. Also
removes dead bower.json/package.json/.eslintrc.json. CI is already on the
shared canon; no src/ change.

chore: add AGENTS.md, drop dead JavaScript-era files

Repos moved from Unisay/* to the purescript-lua org. Update the pslua
flake input and lockfile owner (same rev 94c13ce), the packages.dhall
upstream-lua release URL, and the AGENTS.md links, so nothing relies on
the old-owner redirect.

chore: point pslua + package-set links at purescript-lua org

Wire treefmt via treefmt-nix: nixfmt, dhall format, purs-tidy (.tidyrc.json)
and LuaFormatter for the FFI (.lua-format, kept over StyLua because it
preserves the parentheses pslua's parser needs). `nix fmt` formats; the dev
shell installs a content-based pre-commit hook and CI runs
`nix fmt && git diff --exit-code` (content-based, since the in-place
formatters bump mtime and would trip treefmt --fail-on-change). Lua lines
budget 130 cols, matching the raised `luacheck --max-line-length`. The bulk
of the diff is the first format pass.

chore: add treefmt formatting (nix fmt + pre-commit + CI check)

Replace the dev-shell installer that wrote .git/hooks/pre-commit with a
tracked .githooks/pre-commit wired via `git config core.hooksPath .githooks`.

Fixes three issues with the old hook: it gated on `[ -d .git ]` (false in
worktrees/submodules where .git is a file), it clobbered any existing
.git/hooks/pre-commit on every `nix develop`, and `nix fmt … || exit 0`
swallowed real formatter failures. The new hook skips only when `nix` is
absent (CI is the authoritative gate) and otherwise blocks on a `nix fmt`
failure or reformat.

Toolchain consistency: pin the pslua dev flake input to the current
compiler main across the ecosystem. flake.lock only; the package set
consumes sources + FFI, not this dev input, so no re-tag is needed.

PureScript/JS `forE lo hi f` runs over `[lo, hi)` — lo inclusive, hi
exclusive (Effect.purs doc + JS `for (i = lo; i < hi; i++)`). Lua's
numeric `for i = lo, hi` is inclusive of the upper bound, so the port ran
one extra iteration at i = hi and never produced an empty range
(`forE n n` ran once instead of zero times). Use `for i = lo, hi - 1`.

Adds a Lua 5.1 regression guard (test/regression/effect.lua).
