Single player only runs on its server thread now. --in-frame and
--no-server-thread print a notice, and HORIZON_SERVER_THREAD is ignored.
This deletes the code that only the in-frame path reached: the window's
world loader and local player tick, its portal travel, the loading screen
and ring-by-ring streaming, and the in-frame LAN host (the host player in
the hub, its models of the guests, the reserved uuid). The world-upgrade
progress screen with its Cancel button moves to the server-thread start.
Tools, the harnesses and the docs no longer use the in-frame path.
Closes#6473

* Add the port ledger: vanilla methods next to the Rust functions that port them
tools/port_ledger.py indexes the decompiled sources and the Rust tree into .local/port-ledger/ledger.json and answers where/what/class/coverage queries both ways, with the gaps where a port isn't wired like vanilla (seam, client, class, callee, stale).
* Document the port ledger
* Port ledger: bytecode calls, wider matching, drift, issue and check
Read the game jar's bytecode for exact call targets, constants and ids, and
resolve Rust calls through the receiver's type. Match more methods: same-named
fns in an impl or file named for the class (the impl type must fit the class),
and callees of known pairs linked through the call graph. Leave trivial methods
out of coverage.
New gap kind drift: a port that never names a sound, particle, item, block,
effect or game event its vanilla method uses, or lacks one of its rare numbers.
Seam gaps on the old in-frame path sort last; maths and geometry callees no
longer make seam or callee gaps.
New commands: issue (the classes, Rust code and gaps a bug report points at),
check (what a branch touches, gaps it opens and closes against its base), diff,
and a searchable offline report.html.
* Document the port ledger's new matching, gaps and commands
* Port ledger: class homes, structural matches and the verdict map
Give every vanilla class its Rust home files, weighed from all its matches.
In those files, match a method to the fn that touches the same fields and
reaches the ports of the same callees. Read tools/port_map/*.tsv, where a
person or agent records a verdict for what nothing else finds (port, inline,
missing, skip with a reason), and list the next unanswered batch with todo.
Count field-only constructors as trivial and fold initializer lambdas into
<clinit> and <init>.
* Map the first three batches: animals, inventory screens, world generation
* Document class homes, structural matches and the verdict map
* Map 13 game-logic batches and add map-check
map-check checks verdict-map files against the last build without
rebuilding, so several mappers can check their own rows at once.
* Map the rest of the game logic: classes with no Rust trace, then method batches
* Map client packet handling, entity renderers and models, block renderers
Also let PORT_LEDGER_NO_MAP build without the verdict map, to measure the
automatic matches on their own.
* Map client rendering, particles, sounds and resources
* map-check: accept full Class#method keys
* Map client screens, toasts, recipe book and world screens
* Add a vanilla-parity skill: start parity fixes from the port ledger
* issue: read registry names, so a mooshroom report finds MushroomCow
* Map the remaining vanilla methods: commands, network, packs, advancements and the last ten
* Follow the furnace code to furnace.rs on main; answer Fox.getBreedOffspring
