ci(nix): a stale bun.nix can no longer reach main unnoticed
Moving the bun packages to bun2nix (1db8f763) removed the aggregate deps hash
that used to go stale, but not the second, quieter way a generated file rots.
bun2nix is a pure function of bun.lock, and `bun.nix` is committed alongside it
— but it regenerates ONLY from a local `bun install` that runs lifecycle
scripts. It does not regenerate under `bun install --ignore-scripts`, which is
what every bun install in CI uses, and it cannot regenerate on a merge or
rebase, where git carries someone else's lockfile change past a `bun.nix`
generated before it and reports no conflict.

That is not theoretical. web/bun.nix went onto main holding brace-expansion@5.0.7
(plus two nested entries the `^5.0.8` override had already collapsed) while
web/bun.lock said 5.0.8: the override landed in ec9aa415, the bun2nix branch had
generated bun.nix off the pre-override lock, and the merge kept both. The Nix
build fetches node_modules strictly from bun.nix, so the derivation's offline
`bun install` was asked for a tarball its store cache did not contain and
`nix build .#punktfunk-web` failed. It stayed broken for 553 commits
(2026-07-27 -> 2026-08-05) and was closed by accident, when an unrelated
advisory bump in b79d90b4 happened to rerun a real `bun install`.

Nothing caught it because nothing could: the string "nix" appeared in exactly
one workflow file, and only in a comment about bun2nix breaking a Windows step.

  * scripts/ci/check-bun-nix.sh regenerates each bun.nix from its committed
    bun.lock and diffs, with `--fix` to rewrite them. It reads which packages to
    check out of packages.nix's own `bunNix = src + ...` lines rather than a
    hardcoded list, so a third bun package is covered the day it is added, and
    an empty list is a hard error — a gate that checks nothing passes exactly
    like a clean tree. It also enforces the bun2nix version pin that flake.nix
    and the README only stated: bun.nix has no schema stability across releases,
    so the flake input ref and both package.json devDependencies must agree, and
    generation always uses the pinned version rather than a floating `bunx`.

  * ci.yml gains a `bun-nix` job running it. Deliberately unfiltered and not in
    nix.yml: it needs no Nix, takes under a minute, and the whole point is that
    this drift arrives through commits that look unrelated to Nix.

  * nix.yml is new and is the first CI that evaluates the flake at all —
    `nix flake check --no-build` over every output, then a real build of
    punktfunk-web + punktfunk-scripting, which are the two derivations whose
    inputs churn and the only ones that do not compile Rust. That leg is the
    end-to-end proof the drift gate cannot give: it catches a tarball the
    registry no longer serves, or the codegen going quietly message-less. It is
    path-filtered, has a workflow_dispatch opt-in for the hour-long Rust
    packages, and keeps `pull_request` — flatpak.yml shipped push-only and let
    manifest breakage reach main invisibly for weeks.

The script is POSIX sh (shellcheck-clean, exercised under dash, which is the
CI container's /bin/sh) and avoids process substitution, the parse-time failure
that silently disabled ci.yml's shader SPIR-V gate for 35 commits.
