Two changes per user direction:
- server.properties is reverted (resource-pack lines cleared, require=
false). No more server-pushed pack -- no prompt on join, no kick if
declined, no redundant re-download of a file the launcher already
shipped.
- Adds resource-pack-overrides (Modrinth's gold-standard "auto-enable
bundled resource packs" mod, 8.2M dl, client-only). The Computer
Craft Recreated v1.2.zip already ships in the modpack manifest
(side=client) so it's already in players' resourcepacks/ folder via
the launcher -- RPO will be configured to default-enable it.
The RPO config (`pack/overrides/config/resourcepackoverrides-client.toml`
or similar) lands in a follow-up once we've seen the generated format.
For now this commit just gets the mod into the pack. Bumps to 0.19.4.
