perf: read inventory holders without copying the block - #98
Main profiles, 20 hourly spark dumps 10-30 10:00 → 10-31 05:00 (peak 37 players). Inventory#getHolder() without an argument builds a full BlockState copy when the inventory belongs to a block (chest, barrel, double chest), and every plugin's click/open listener calls it again. Over the 20 h that cost ~200 s of main-thread time, mostly as short stalls on clicks in heavy containers; one click at 04:01 took 2.0 s. In ActivityTF: ReferralGui.onClick 1.5 s.
Change
5 calls → getHolder(false).
Tests: test-only HolderLookupPatch via a JUnit LauncherSessionListener.
For plugin menus the holder is the plugin's own object, so the result is identical. For real block inventories the code only type-checks or reads the holder, so the live state gives the same answer. Nothing players see changes.
Testing
1075 tests pass; locally only the coverage gate fails, on lines two tests skip on Windows.
Dev (TFMCDev01, 10-31 from 11:47 UTC): this PR's jar ran together with the other 12 jars from this round (VF, SF, MusicalInstruments, Magic on the Blood Magic branch, TLibs, GunsAndGadgets, Thievery, BirdMessenger, Surgery, CompanionPets, ActivityTF, MarketBlock), through two restarts. No error from any of them in the log. Bot TestChar1:
A chest, a double chest and a barrel, each full of shulker boxes of written books: open, pick up and put back, shift-click both ways. Every plugin's click/open listener ran; the stacks stayed intact and nothing was logged.
/faction list (row click works), /referral and /activity menus opened and worked.
The activity and referral menu listeners run on every inventory click
and drag. Each plain getHolder() call copied the whole block state when
the inventory belonged to a chest or barrel. On Main ReferralGui.onClick
cost 1.5 s over 20 hours.
The checks now use getHolder(false), which hands back the same holder
without the copy. Both menus have their own holder, so the result is the
same object as before. No call site changes a block state, so none were
left as they were.
MockBukkit throws on getHolder(false), so a JUnit session listener
patches its inventories to return their plain holder.

Bug Fixes
Improved handling of clicks and drags in activity and referral menus, helping these interactions respond more consistently.
Improved the handling of activity-menu clicks that trigger commands, including checks performed when the inventory closes.
The activity and referral GUI handlers, and the activity command check, now use getHolder(false). A JUnit launcher-session listener installs a test patch for InventoryMock.getHolder(boolean).
TF-Minecraft/ActivityTF#97: Adds the ReferralGui click and drag handlers that this pull request updates.

Merge Risk: Low · previous review a651a
The holder lookup changes have no established production regression. Remaining risks are confined to test instrumentation failures, so merging is reasonable with owner awareness and follow-up on patch installation handling.

HolderLookupPatch returns the same holder for both boolean values. The GUI tests assert only the resulting behaviour, so a change from getHolder(false) to getHolder(true) would pass. Add verification that the handlers pass false.

Byte Buddy reports a failed retransformation only to its listeners and
returns normally, so the patch counted as installed even when
InventoryMock kept its throwing getHolder(boolean). It now marks itself
installed only after InventoryMock was transformed, and stops the test
session with a clear error otherwise (CodeRabbit).

onTransformation fires before the JVM applies the new bytes, so a
rejection in retransformClasses reaches only onError. The patch now fails
the test session in that case too (Opus review).
