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.

Removes docs/performance/java-perf-mods.md (a survey of eight Java
performance mods' techniques) and docs/research/java-mod-compat.md (notes
on how Fabric, NeoForge and Mixin work, with a list of mods to port).
Links to them now point at mods.md, which says in two lines why Java jars
don't run in Horizon.
docs/modpacks.md no longer lists a mod's decompiled code as an input of a
port: a mod's code is never decompiled, read, quoted or paraphrased, and
ports are written from the mod's observed behaviour (the oracle and the
harness), its own data files and its public documentation only.

Importing a modpack from the Mods page (or `mods install`) now ports it right away
for the selected version, so Play works straight after. port-pack leaves a
namespace two carried mods both claim to none of them (YUNG's mods all ship
`yungsapi`, which made the game drop three of them), and the launcher applies
the game's first-wins rule before it starts a pack, listing what it left off.
Measured on Vanilla Perfected, Slimes Adventure and All the Mods 10 (docs/modpacks.md):
2, 20 and 42 mods ported, every world loads, no crash.

mod_browser_harness.py searches, checks and installs a mod through the launcher's
mods CLI in a scratch game folder, opens a world with it offscreen, places one of
its blocks and crafts one of its recipes on a crafting table, and times the world
load with and without it. Macaw's Fences: check 4.0 s, install 3.1 s, world load
5.4 s -> 7.3 s, hedge placed, 4 crafted.

A result's title opens its page in the launcher: icon, authors, downloads,
followers, licence, verdict (for a Java mod, what ports and what doesn't) and
Install, links, then Description (Markdown), Gallery and Versions tabs
(browser::details, Source::details on Modrinth's project and members).
Filters: sort (relevance, downloads, follows, newest, updated), loader, game
version, environment and categories, from the source's tag lists.
Icons and gallery images are fetched at run time over HTTPS from the sources'
image CDNs only, size-capped, decoded and scaled to PNGs in a 128 MB disk cache
(browser::images); a placeholder shows until they arrive. Vanilla's mark is a
grass block drawn from the player's prepared game files. Modrinth's logo isn't
shown: its branding is all rights reserved without written permission.

Ludovic dropped CurseForge for now (its API needs a paid key). The Mods page shows
"CurseForge (coming soon)" beside the Modrinth switch, disabled and inert;
browser::sources() is Modrinth only, so no search or install goes to CurseForge,
and `--source curseforge` says it is coming soon. Text that asked for a key or
an environment variable now says CurseForge support is coming soon. Importing a
CurseForge zip or instance still works; jars only CurseForge serves are listed
as "CurseForge downloads coming soon".

The Mods page gets a Mods tab: Fabric, NeoForge, Forge and Quilt mods for 26.3
(1.21 and later with Show everything). Each result's jar is downloaded (allowed
CDNs, checksum), checked with horizon-port-pack (Works, Partly, Doesn't run, with
what ports and what doesn't) and the answer cached per file. Install copies the
carry into horizon-mods/<id>/ and turns it on in horizon-mods.txt, with required
mods that port; libraries with nothing to port are listed as not ported; id or
namespace clashes are refused. Remove deletes it and turns it off.
The Modpacks page becomes the Mods page's Modpacks tab: imported packs first,
then the search. CLI: mods search --kind mod, mods check <project>.

A Mods page between Versions and Modpacks: resource packs, shader packs and
modpacks as tabs, a search field, Show everything, and Modrinth / CurseForge
once CurseForge has a key. Results are index rows with summary, author,
downloads, source, licence and how well each runs (with the reason), Page and
Install (Import for a modpack, which then shows on the Modpacks page).
Installed packs list their version, source, file and the checksum they were
checked against, with Update and Remove. Searches, installs and update checks
run on threads; stale search answers are dropped.

browser::installed installs a pack and its required dependencies into
resourcepacks/ or shaderpacks/, every file checked before any download
(a dependency that is a Java mod stops it) and checksum-verified on the
way in; mod-browser.json records source, version, file and checksum.
Update swaps the file, remove deletes only what the browser installed (a
player's own file of the same name is never overwritten). A modpack is
downloaded, checked, and imported through the Modpacks page's pipeline.
The CLI gains `mods list|search|install|update|remove`.

The launcher's core gains `browser`: search Modrinth for what Horizon loads
(resource packs, Iris/OptiFine shader packs, modpacks; never Java mod jars),
say how well each result runs, pick the newest version that runs, and
download a file only from Modrinth's or CurseForge's file servers, with a
plain file name, kept only when its size and SHA-512 (SHA-1 on CurseForge)
match. CurseForge is a pluggable source that stays off until an API key
exists (HORIZON_CURSEFORGE_API_KEY at run time or build time; the launcher
workflow passes the repository secret). docs/mod-browser.md.
