feat(installer): modules.conf registry + sentinel-based code generation
Collapse 5 manual touch points per optional app module (counter, checklist,
summary, conflict check, dispatch in tui-install.sh + answerfile generator +
docs table row) into a single source of truth at setup/modules.conf.
- setup/modules.conf: 80-module registry (id|category|description|default|excludes)
with sensible defaults (python, firefox-browser, onlyoffice) and conflict pairs
(plymouth-custom ↔ plymouth)
- setup/sync-modules.sh: scans apps/*.sh, stubs any IDs missing from modules.conf
- setup/generate-modules.sh: regenerates all sentinel regions from modules.conf
(supports --dry-run); fixes Python re.sub backslash-n corruption via lambda repl
- tui-install.sh: 5 sentinel regions added (module-counters, module-checklist,
module-summary, module-conflicts, module-dispatch); fixes 19 modules missing
from count_steps() and mail-notmuch/caldav-sync missing from SUMMARY
- generate-answerfile.sh: module-checklist sentinel; list-height now auto-computed
- docs/md/modules.md: per-category sentinels; all sections regenerated from conf
- Renames: prismlauncher→prism, freeipa-image-builder→freeipa-image,
firefox→firefox-browser, zed→zed-ide; moves python/zfs/wprs into apps/
