Make the repo Slackware compatible

[deepfriedmind]

This facilitates installing/updating with https://github.com/ich777/un-get

Note: I've changed it so that README.md.template gets copied to README.md, and then the template string substitutions are performed. This means that future changes to the README should be made in the template file. I hope that's okay with you.

Summary by CodeRabbit

• New Features

  • Published a Slackware repository for Fish; package now available under slackware/fish with file list and checksums.

• Documentation

  • Expanded README with two installation methods (manual and via un-get), instructions to set Fish as default shell, and clarified "About Fish".
  • Added a README template for consistent, environment-driven release notes.

• Chores

  • CI workflow now builds the Slackware repo, generates repository metadata, updates README from the template, and publishes the package.

Walkthrough

Adds a Slackware repo metadata generator script, integrates README templating and repo updates into the build workflow, and adds repository metadata entries and a README template for the fish package.

Changes

Cohort / File(s)	Summary
Repo metadata script .github/scripts/generate-repo-files.sh	New shell script that enumerates package files, writes atomic FILE_LIST and CHECKSUMS.md5 (using stat/md5sum), excludes temp files, and is robust to missing files/errors.
GitHub Actions workflow updates .github/workflows/build-fish.yml	Workflow steps added/changed to create slackware structure, move package into slackware/fish, generate metadata via the new script, generate README.md from README.md.template (placeholder substitutions), and commit/push repo changes; release artifact path updated.
README and template README.md, README.md.template	README.md reflowed with explicit install methods and default-shell instructions; new README.md.template added with placeholders {{PKG_FILE}}, {{UPSTREAM_FILE}}, {{REPO_URL}} for workflow-driven README generation.
Slackware repo outputs slackware/CHECKSUMS.md5, slackware/FILE_LIST	Added entries for ./fish/fish-4.1.1-x86_64-1_da.txz to CHECKSUMS.md5 and FILE_LIST (permissions, size, timestamp recorded).

Poem

In bins and bytes I twitch my nose,
I tally files where checksum goes.
A temp file hops, then swaps in place,
README reads its templated face.
I push, I leap—repository grows. 🐇✨
