A developer of Iris showed that Horizon's shader pack code was written from
Iris's source. This removes it: the horizon-shaderpack crate, Java pack
loading and its render stages, Horizon's own WGSL packs and the example
packs, the Shader Packs screen and its option, the launcher's shader pack
browsing and installing, and the docs about them. Shader packs may come
back later as a clean-room rewrite.
The vanilla renderer and its post-processing (resolution scale, FXAA) are
unchanged. Options files that name a pack load and drop the key; the
launcher reads manifests that list a shader pack, and files in
`shaderpacks/` are never deleted.

Drop the Horizon menu style (options_horizon.rs, front.rs, the live title
backdrop and its post grade, the launcher's menu-style setting, CLI and MCP
tool). Every screen is vanilla's. Horizon's own settings hang off vanilla's
Options the way mods add theirs: Horizon Settings... and Mods... take the
Telemetry/Credits slots, and Horizon Settings opens Graphics, Advanced
Graphics, Shader Packs, Controller Settings, Extras and Mods, each a vanilla
options list with tooltips. Play with friends moves behind vanilla's Friends
buttons: the pause menu's opens Play with Friends (share, copy, stop), the
title screen's opens Join a Friend, and Direct Connection takes a full code.
Old files load as before: horizon.txt's menuStyle line and
horizon-graphics.txt's level line are ignored.

A new Horizon Extras option, Lighting > Dynamic lights (`dynamicLights`,
off by default): a torch, lantern or other light-emitting item held by a
player or mob, dropped as an item, or any entity on fire lights the blocks,
entities and hand around it, as LambDynamicLights and OptiFine do.
Client-only and at render time: the light engine, chunk meshes and saves
never see it. Each frame the game picks the 16 sources nearest the camera
(dynamic_light::select) and passes them in Globals; terrain.wgsl and
entity.wgsl raise each vertex's block light to `level - distance` when that
is brighter. Off, the count in globals.time.z is 0, nothing is gathered and
the shaders' loop runs zero times, so no pipeline is rebuilt either way.
An item glows like its block's default state (torch 14, lantern and
glowstone 15, lit redstone torch 7); a lava bucket 15; burning entities 15.

Classic Extras laid every setting out as a full-width button. Pair each
section's buttons as vanilla's OptionsList.addSmall does (the same layout as
Video Settings), and shorten "Lower sensitivity while zoomed" to "Slower
turning" so it fits a half-width button.
Horizon's Extras page shows a switch's own settings (Zoom key, Minimap size,
FPS corner...) only while that switch is on, so it stays one row per extra
as the list grows. Classic keeps every button, as vanilla screens do.

The Extras page's Inventory section gains "Sort buttons" (sort, off) and
"Sort key" (sortKey, unbound). A small button right of a chest, barrel,
ender chest or shulker box title sorts the container; one right of the
"Inventory" line sorts the main inventory (the hotbar stays). The key
sorts the part under the cursor.
inv_sort::plan merges partial stacks, then orders the stacks by creative
tab order (the search tab's), then name, full stacks first, using only
left PICKUP clicks with an empty hand: the game sends them as ordinary
clicks, so vanilla servers accept them. A unit test replays the plans
through the menu engine on 40 random chests.
The Extras page binds any extra key the way it bound the zoom key
(Item::key_name, Extras::set_key).

The Extras page gains an Inventory section with "Mouse Tweaks controls"
(mouseTweaks, off) and "Scroll wheel moves items" (mouseTweaksWheel). In
the player inventory and chest-like containers, locally and on servers:
- right-drag holding a stack puts one item in each slot entered, at once;
- left-drag holding a stack gathers the slots of the same item into the
hand, while vanilla's drag covers one slot (a drag over empty slots
still splits as vanilla does); with Shift they are quick-moved;
- Shift + left-drag with an empty hand quick-moves every slot entered;
- the wheel over a slot moves one item to the other side (down) or
brings one back (up).
Every action is ordinary slot clicks: the menu engine's, or ContainerClick
packets for any slot (remote_slot_click, factored out of remote_click).
With the extra off each hook returns at once.
horizon-ctl gains drag-at and scroll-at, which send the window events of
a mouse drag and of wheel steps, to test these and vanilla's drags.

Classifies the online-mode login outcomes from #161: invalid session,
banned from playing online, multiplayer disabled, no account signed in
and the server failing to verify the username are never retried;
unreachable session servers (the client's or the server's) are. A retry
of an online-mode server joins with the account held in memory for the
whole run.

The zoom key went to the zoom on every screen, so with zoom on, Z could
not be typed in screens with text fields that share the game's key
handler. Now it zooms only while playing with no sign or book open, lets
go when a screen opens, and always passes the key on, like a vanilla key
mapping. A vanilla mapping bound to the same key still acts; the Extras
page marks the zoom key "Also bound" and names it.

An Extras section in Horizon's Options holds optional additions saved in
horizon-extras.txt beside options.txt. Zoom divides the field-of-view
target vanilla's Camera.tickFov eases toward (the spyglass path), with a
wheel-adjustable level and lower mouse sensitivity; scoping keeps the
spyglass view. The FPS counter (with minimum and 1% low) and the keystroke
overlay (WASD, space, mouse buttons with clicks per second) draw in the
HUD layer, hidden with F1. docs/extras.md describes all the extras.
