feat(pack): add 14 client-side mods and 12 supporting libraries

Client QoL / visual / audio:
  grassier-grass, perception, inventory-particles, fwa,
  advancement-plaques, keybind-atlas, held-item-tooltips, zume, sound,
  extreme_sound_muffler, now-playing, cat_jam, loot-journal,
  travelers-titles

Libraries:
  moonlight, shatterbyte-lib (OctoLib), runiclib, delight-lib,
  lodestonelib, mossylib, puzzles-lib, mru, fragmentum, smartbrainlib,
  blueprint, coroutil

perception and sound carry side = "client", so neither is installed on the
dedicated server.

Two of the libraries are dependencies that Modrinth metadata does not
declare, so packwiz cannot resolve them automatically: perception hard-links
OctoLib and dungeons_delight links runiclib. Adding them up front means the
later stages resolve without a missing-class crash.
