skills: rename pkgrepo -> f3s-pkgrepo and rocky-vm-setup -> f3s-rocky-vm-setup

Extend the f3s- prefix to the two remaining f3s-scoped siblings so the whole
homelab family groups together. Both are f3s-specific: pkgrepo IS
pkgrepo.f3s.buetow.org, and rocky-vm-setup documents the 'rocky' VM on the f3s
host f3.

- git mv both skill dirs (history preserved); update name: frontmatter; add the
  'Part of the f3s homelab skill family' note to both descriptions.
- Rewrite every reference to the *skills*: backtick mentions (`pkgrepo` ->
  `f3s-pkgrepo`, `rocky-vm-setup` -> `f3s-rocky-vm-setup`), markdown cross-links
  (../pkgrepo/ -> ../f3s-pkgrepo/, etc.), the f3s hub Related-skills block and
  description, and skill-maintenance's index-pattern example.
- Left references to the package REPOSITORY (pkgrepo.f3s.buetow.org, 'the custom
  pkgrepo') unchanged — those name a service, not the skill.
- Verified all 114 relative links resolve. Plan doc updated to record the rename.

-# Client Setup
-
-How to configure each OS to install packages from `pkgrepo.f3s.buetow.org`.
-
-## FreeBSD (f0–f3)
-
-Custom repo is configured alongside the official FreeBSD repos.
-
-File: `/usr/local/etc/pkg/repos/custom.conf`
-
-```
-custom: {
-  url: "https://pkgrepo.f3s.buetow.org/freebsd/FreeBSD:15:amd64/latest",
-  mirror_type: "NONE",
-  signature_type: "NONE",
-  enabled: yes
-}
-```
-
-### Using packages
-
-```sh
-doas pkg update
-doas pkg install <package-name>
-doas pkg upgrade                  # upgrade all, including custom packages
-doas pkg install -fy <package>    # force reinstall (same version)
-```
-
-### Setting up a new FreeBSD host
-
-Pipe via stdin to avoid csh quoting issues:
-
-```sh
-cat <<'REPO' | ssh -p 22 <host>.lan.buetow.org 'doas mkdir -p /usr/local/etc/pkg/repos && doas tee /usr/local/etc/pkg/repos/custom.conf > /dev/null'
-custom: {
-  url: "https://pkgrepo.f3s.buetow.org/freebsd/FreeBSD:15:amd64/latest",
-  mirror_type: "NONE",
-  signature_type: "NONE",
-  enabled: yes
-}
-REPO
-```
-
-## OpenBSD (blowfish, fishfinger)
-
-Custom repo is configured via `PKG_PATH` in `/root/.profile`, deployed by `rex pkgrepo_setup`.
-Official OpenBSD packages still install normally via `/etc/installurl`.
-
-```sh
-export PKG_PATH="https://pkgrepo.f3s.buetow.org/openbsd/7.8/packages/amd64/"
-```
-
-### Using packages
-
-```sh
-doas pkg_add <package>       # installs from custom repo (signed with signify)
-doas pkg_add -u <package>    # update to latest version
-```
-
-### Setting up a new OpenBSD host
-
-Two things needed:
-
-1. **Signify public key** — copy from an existing host:
-   ```sh
-   scp rex@fishfinger.buetow.org:/etc/signify/custom-pkg.pub /tmp/
-   scp /tmp/custom-pkg.pub rex@<newhost>:/tmp/
-   ssh rex@<newhost> "doas cp /tmp/custom-pkg.pub /etc/signify/custom-pkg.pub"
-   ```
-
-2. **PKG_PATH** — run the Rex task from `~/git/conf/frontends`:
-   ```sh
-   rex pkgrepo_setup   # adds PKG_PATH to /root/.profile on all frontends
-   ```
-
-Update `PKG_PATH` whenever the OpenBSD version changes (currently 7.8).
-
-### Package signing
-
-OpenBSD packages are signed with `signify(1)` via `pkg_sign`:
-- **Private key**: `/etc/signify/custom-pkg.sec` on fishfinger (build host)
-- **Public key**: `/etc/signify/custom-pkg.pub` on all OpenBSD clients
-- Signing happens automatically during `make pkg-openbsd` / `make pkg`
-- `pkg_add` verifies the signature — no `-D unsigned` needed
-
-## NetBSD (pi0, pi1)
-
-No persistent repo config needed — install/update straight from the package URL (repo is unsigned):
-
-```sh
-export PATH=/usr/sbin:$PATH   # pkg_* live in /usr/sbin, not in the default non-interactive PATH
-doas pkg_add https://pkgrepo.f3s.buetow.org/netbsd/10.1/packages/aarch64/dtail-4.3.2ng.tgz    # first install
-doas pkg_add -u https://pkgrepo.f3s.buetow.org/netbsd/10.1/packages/aarch64/dtail-4.3.2ng.tgz # update to newer version
-```
-
-Notes:
-- Same-version reinstall: `pkg_add -u` skips it — `doas pkg_delete dtail` first, then `pkg_add` again
-- `pkg_summary.gz` is published alongside the packages, so the repo URL could also be added to `/usr/pkg/etc/pkgin/repositories.conf` for pkgin; today plain `pkg_add` is used
-- Version in the URL path must match the host OS release (currently 10.1) and the arch is `aarch64` (`uname -p`)
-- pkgsrc packages from cdn.netbsd.org still install normally via pkgin — the custom repo lives under a different prefix (`/` with files in `/usr/local`, `/etc`) and doesn't conflict
-
-## Rocky Linux (r0–r2, pi2–pi3)
-
-`pi0`/`pi1` run NetBSD (see above and the `f3s-raspberry-pi` skill's `bootstrap-netbsd-pi.md`) and are not Rocky clients of this repo.
-
-Architecture-specific repo URLs:
-- `https://pkgrepo.f3s.buetow.org/rockylinux/9/x86_64/`  (r0–r2)
-- `https://pkgrepo.f3s.buetow.org/rockylinux/9/aarch64/` (pi2–pi3)
-
-### Persistent repo file
-
-Create `/etc/yum.repos.d/f3s-dtail.repo`:
-
-```ini
-[f3s-dtail]
-name=f3s DTail
-baseurl=https://pkgrepo.f3s.buetow.org/rockylinux/9/$basearch/
-enabled=1
-gpgcheck=0
-repo_gpgcheck=0
-```
-
-Then:
-
-```sh
-sudo dnf makecache
-sudo dnf install dtail
-sudo dnf upgrade dtail
-```
-
-### Temporary one-off usage (no persistent repo file needed)
-
-```sh
-sudo dnf repoquery \
-  --disablerepo='*' \
-  --repofrompath=f3s-dtail,https://pkgrepo.f3s.buetow.org/rockylinux/9/$(uname -m)/ \
-  --enablerepo=f3s-dtail \
-  dtail
-```
-
-Do **not** pass `--repofrompath` when the persistent repo file already exists — dnf errors with "listed more than once".
