## Description
Find-and-replace 2026.1.1 -> 2026.2.1. This gets us 2026 field layouts
[among other
things](https://github.com/wpilibsuite/allwpilib/releases/tag/v2026.2.1)
<!-- What changed? Why? (the code + comments should speak for itself on
the "how") -->
<!-- Fun screenshots or a cool video or something are super helpful as
well. If this touches platform-specific behavior, this is where test
evidence should be collected. -->
<!-- Any issues this pull request closes or pull requests this
supersedes should be linked with `Closes #issuenumber`. -->
## Meta
Merge checklist:
- [ ] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [ ] The description documents the _what_ and _why_
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with settings back to v2025.3.2
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added

Bump to wpilib 2026 beta. This does not bump our pythonlib, as robotpy
hasn't come out yet.

Occasionally, the sim projects are capable of simulating current draw of
over 600A, which triggers a condition in
`BatterySim::calculateDefaultBatteryLoadedVoltage` that limits the
minimum measured battery voltage to 0V (to prevent it from going
negative).
When battery voltage measures 0, this causes NaN values to propagate
through the drivetrain model, making sim inoperable. Specifically, [this
is the
line](https://github.com/PhotonVision/photonvision/blob/master/photonlib-java-examples/aimandrange/src/main/java/frc/robot/subsystems/drivetrain/SwerveDriveSim.java#L452)
that causes the initial NaN values in simulation.
This PR is posed as a patch to ensure that simulation doesn't break.
Fixes#1564. Also copies vendordep JSONs to the examples as advised by
Thad. Removes unused shared/javacpp/setupBuild.gradle. Also removes
unnecessary `chmod +x gradlew` from CI workflows.
