- .ghci: -j1 → -j4 for parallel module compilation
- scripts/compile-check: auto-detect high-RAM hosts (>16GB) and
set GHCRTS="-A256m -M20g" to reduce GC pressure
- devenv.nix: update comment only (GHCRTS still set at runtime)

Root cause: devenv shell reads devenv.nix only; IHP's Haskell setup is in
flake.nix's devenv.shells.default which is only loaded by nix develop.
Fix: create devenv.yaml to register IHP as a devenv input (pinned to the
same rev as flake.lock) with overlays.default applied. Update devenv.nix
to set IHP_LIB/IHP env vars and enable languages.haskell with pkgs.ghc
(IHP-overlay GHC) + all project packages; add ghcid explicitly.
devenv.lock pins IHP at df3922d (matches flake.lock).
scripts/compile-check: updated header comments and added IHP_LIB echo;
switches from ghcid to ghci one-shot (ghcid not available in all shells).

- Add Web/Controller/Prelude.hs (was missing; 8 controllers failed to import it)
- Add .ghci-core and scripts/compile-check-core to compile Layer 1+2 in
isolation without loading Main.hs or any controller/view (Layer 3)
- Fix Application/Helper/BottleneckDetector.hs: replace coerce :: Id' -> UUID
with unpackId (IHP Id' wraps a type family; Data.Coerce cannot cross it)
- Fix devenv.nix: add pkgs.nodePackages.tailwindcss so devenv process scripts
find the tailwindcss binary (devenv v2 builds scripts with only local packages)

devenv v2 requires devenv.nix to exist even when the full shell
configuration lives in flake.nix via IHP's devenv.flakeModule.
Contains project-specific overrides (GHCRTS, tailwind process);
IHP core (postgres, ghcid, RunDevServer) still comes from the flake module.
