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.

+
+## Building taskwarrior from source
+
+Rocky 9 does not ship `task`/`taskwarrior`. v3.x requires Rust; v2.6.2 compiles cleanly.
+
+```sh
+# deps
+dnf install -y cmake gcc-c++ make libuuid-devel gnutls-devel libssh2-devel
+
+# build
+git clone --depth 1 --branch v2.6.2 \
+  https://github.com/GothenburgBitFactory/taskwarrior.git /tmp/tw-build
+cd /tmp/tw-build
+cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
+cmake --build build -j$(nproc)
+cmake --install build
+
+# verify
+/usr/local/bin/task --version   # 2.6.2
+```
+
+## First-run fish setup
+
+After the dotfiles `home` task deploys fish config, some plugins and binaries are expected but not yet present:
+
+```sh
+# 1. Install fisher (fish plugin manager)
+curl -sL https://raw.githubusercontent.com/jorgebucaran/fisher/main/functions/fisher.fish | source
+fisher install jorgebucaran/fisher
+
+# 2. Install the fzf.fish plugin (provides fzf_configure_bindings)
+fisher install PatrickF1/fzf.fish
+
+# 3. First-run taskwarrior creates ~/.taskrc
+yes | task >/dev/null 2>&1
+
+# 4. Install Go tooling binaries (run as paul)
+for prog in ask hexai hexai-lsp-server hexai-tmux-action hexai-mcp-server; do
+    go install codeberg.org/snonux/hexai/cmd/$prog@latest
+done
+for prog in tasksamurai timesamurai gt; do
+    go install codeberg.org/snonux/$prog/cmd/$prog@latest
+done
+for prog in gitsyncer gos snonux; do
+    go install codeberg.org/snonux/$prog/cmd/$prog@latest
+done
+# (foostore, loadbars, totalrecall, goprecords may need X11/GL deps for GUI — skip on headless)
+```
+
+## tmux 3.2a compatibility note
+
+The dotfiles `tmux.conf` includes `set -g extended-keys-format csi-u` (tmux 3.3+). On rocky this line is automatically stripped by the `home_tmux_rocky` Rex task. If you deploy manually, remove or comment out that line.
