Both branches changed how the harness finds the mod jars: resolve every jar
through jar_path (jars, then pack-jars) and keep the profile packs check.

From spec-yungsapi rev 3 §3, §3.1 and §3.2 (impl-questions IQ-2, IQ-3):
- the start piece does not count toward max_count;
- is_priority entries are tried first, in the pool's shuffled order, without
a weighted draw; min_required_depth skips a pick (no draw) while the parent
piece is shallower; ignore_bounds places without the free-space test (its
box is still taken, IQ-12);
- the fallback was already shuffled only when reached.
The port no longer counts these three fields as lost. The layout harness gets
yung-probe and yung-probe2: the spec team's probe pack (built from the oracle
profile) carried as a mod, compared start by start with the oracle's census:
384 of 384 and 32 of 32 starts match.

The mod world now takes each saved start whose pieces are all jigsaw pieces
as the oracle saved it (chunk_dump's HORIZON_SAVED_STARTS, through a new
GeneratorWorker::use_saved_start and PoolPiece::from_saved), so the blocks
are checked whatever the layout: Lithostitched lays jigsaws out its own way
(spec-lithostitched OPEN-L5) and the layout harness checks layouts apart.
Lithostitched's wrapper elements place their delegate; 1.21.1 block states
are read in 26.3's shape.
Counts are split between positions inside a piece's box and around them
(terrain adaptation, decoration), and every mismatch class is written to
.local/structure-layout/<profile>/blocks-report.json.
A CTOV profile carries Lithostitched and ChoiceTheorem's Overhauled Village
from a pack's jar folder (.local/structure-oracle/pack-jars).

Clean-room (spec-yungsapi.md §2, §3, §5; no mod source read; the legacy
files were deleted unread). horizon-port-pack's new `yung` module carries
`yungsapi:yung_jigsaw` structures and `yungsapi:yung_single_element` pool
elements as the mods write them, so players' packs reach the YUNG draws of
the jigsaw assembler. Fields whose behaviour the specification leaves open
(adapt_noise, max_y/min_y, enhanced terrain, element conditions, modifiers,
priorities, depths, ignore_bounds) are counted as lost by name. YUNG's
other structure, placement and processor types go to the general code
(unsupported or dropped) until the specification covers them.
Deleted: legacy_structure_mods/yung.rs, horizon-world's structure/yung.rs,
the `horizon:yungsapi` keys and `horizon:disables`, which nothing writes
now. Two test initializers of the removed field (enhanced_terrain.rs,
piece_limited.rs) were removed by line from the compiler's error positions.
The layout harness now carries the mods through `horizon-port-pack carry`:
82 of 84 Better Dungeons starts match the oracle piece for piece, as before.

Clean-room, from spec-yungsapi.md §2.1 and §3.1 (no mod source read).
A `yungsapi:yung_jigsaw` structure lays out with the jigsaw assembler and
YUNG's draws: the start pool's file entries shuffled, then the rotation,
then a weighted pick in the shuffled order; each jigsaw's target pool is
drawn by weight from its shuffled entries without replacement, an element
whose `name` already has `max_count` pieces skipped at no other draw.
`yungsapi:yung_single_element` places what a single element places; its
pool entry carries the name and limit.
tools/test_structure_layout_parity.py --profile betterdungeons reads the
mod's own data from its jar into an overlay of the 26.3 resources and
compares the mod world's pieces: 82 of 84 Better Dungeons starts match
piece for piece (60 small, 11 skeleton, 11 zombie dungeons, up to 790
pieces); the other 2 sit in 26.3's sulfur_caves, which 1.21.1 lacks.

The clean-room structure oracle saved, for 31 starts of vanilla structures
(villages, outposts, trial chambers, shipwrecks, ruined portals, desert
pyramids over seeds 1234, 2 and 42), the no-mod world's pieces. A new
structure_pieces probe lists the starts a chunk owns, piece by piece, and
tools/test_structure_layout_parity.py compares them with those saves.
22 of the 31 match piece for piece (every village and outpost that 26.3
still places there, and the horizontal boxes of the code-built pieces).
The other 9 differ between 1.21.1 and 26.3 themselves: 26.3 vanilla's own
pieces there (VanillaChunkGenerationOracle scan) equal Horizon's for all 18
starts that differ from 1.21.1. No vanilla jigsaw fix is needed.
Templates now keep the id they were loaded under, so a piece names its
element.
