FlatLaf is loaded at runtime through slimjar like the other libraries.
Every studio window now opens with FlatLaf's dark look tuned to the
IntelliJ New UI colours, and shares a small kit of controls: a flat
toolbar, toolbar buttons and tabs, search boxes, a status bar and the
rounded cards drawn over maps.

Paper still provides Adventure at runtime. Every Adventure method Iris calls has the same signature in 4.17 and 5.2.0, so older servers keep working.

Adds the v26_1_R1 binding, which covers both versions. 26.x servers are
not obfuscated and need Java 25, so the build moves to Gradle 9.5.1 and
paperweight-userdev 2.0.0-beta.21, and the binding compiles against the
26.1.2 dev bundle with a Java 25 toolchain while everything else stays on
Java 21.
On 26.x every world is a dimension inside the main level, so the binding
provides DimensionWorldStorage:
- world folders resolve to <level>/dimensions/<namespace>/<key>
- data packs go to the level's datapacks folder
- Iris data in a pre-26.1 world folder is moved into the dimension
before Paper imports the world and deletes the old folder
- "main=true" swaps the world in as the level's overworld instead of
changing level-name
Also:
- INMS compares 1.x and 26.x versions in release order
- data pack formats 101 (26.1.2) and 107 (26.2), declared with
min_format/max_format from format 82 on
- dimension types get the fields 26.1 added
- the Java safeguard accepts Java 25

Core now compiles against paper-api instead of spigot-api. PaperLib is
replaced by Paper's native async chunk and teleport API, and the Spigot
fallbacks (Medieval pregen method, sync chunk loading) are removed.
Adventure is no longer bundled and relocated: Paper ships it and every
CommandSender is an Audience, so the BukkitAudiences wrapper and ShadeFix
go away.
Iris now refuses to enable on servers without the Paper API, with a clear
message instead of failing later at runtime.
