Add tilia

Checklist:

• Meaningful commit message, eg add my-cool-package (please don't mention build-constraints.yml)
• At least 30 minutes have passed since uploading to Hackage
• If applicable, required system libraries are added to 02-apt-get-install.sh or 03-custom-install.sh
• (recommended) Package have been verified to work with the latest nightly snapshot, e.g by running the verify-package script
• (optional) Package is compatible with the latest version of all dependencies (Run cabal update && cabal outdated)

The script runs virtually the following commands in a clean directory:

  stack unpack $package-$version # `-$version` is optional
  cd $package-$version
  rm -f stack.yaml && stack init --resolver nightly --ignore-subdirs
  stack build --resolver nightly --haddock --test --bench --no-run-benchmarks

I've just allowed tar-0.7 but there is nothing I can do about ghc-lib-parser.

Right, but then I fear we maybe need to wait for nightly to move to ghc 9.14.

ghc-lib-parser-9.14.1.20251220 is out of bounds for:

• fourmolu-0.19.0.1 (>=9.12 && < 9.13)
• hindent-6.3.0 (>=9.2 && < 9.13)
• hlint-3.10 (>=9.12 && < 9.13)
• ormolu-0.8.0.2 (>=9.12 && < 9.13)

The newer versions of fourmolu, ormolu require newer Cabal that we couldn't provide with ghc 9.12 - so if we like to add tilia we would need to drop the four packages above. So basically we have three options:

1. Sit and wait for nightly moving to ghc 9.14
2. Replace the 4 mentioned packages with tilia
3. Make tilia compatible with ghc-lib-parser-9.12.3.20251228

I think the right thing to do here is to wait.
