…h-http (#8465)

Fixes #7826

Changes:
- Upgrade sbt version from 0.13.18 to 1.10.7 in launcher-package/project/build.properties
- Remove dead dispatch-http 0.8.10 dependency from plugins.sbt
- Update sbt-native-packager from 1.7.6 to 1.10.4 (com.github.sbt)
- Update sbt-pgp from 2.1.2 to 2.3.1
- Replace all dispatch.classic._ HTTP calls with Java URL.openStream()

The dispatch-http library is dead and doesn't support sbt 1.x. This change
uses standard Java networking APIs for HTTP downloads, eliminating the
dependency on outdated libraries.

All HTTP download operations now use:
- java.net.URL.openConnection()
- InputStream with buffered reading
- Proper resource cleanup with try-finally blocks

- Removes the sbt-export-repo plugin dependency
- Defines exportRepo and exportRepoDirectory settings locally
- Removes ExportRepoPlugin from dist project
- Fixes exportRepo task to not reference itself

* fix: Update PackageSignerPlugin.scala for sbt 1.x compatibility
- Use withExtension instead of copy(extension = ...) for Artifact
- Update Classpaths.publishConfig to use sbt 1.x signature with all required parameters
- Use new slash syntax for scoped keys (pgpSigner / skip instead of skip in pgpSigner)

* fix: Use computed status instead of status key in PackageSignerPlugin

* fix: Use withRevision instead of copy for ModuleID in build.sbt

- Add scala.sys.process._ import for shell command execution (! method)
- Fix resolvers setting to use new slash syntax and proper Option handling
- Fix publish/publishLocal to use {} instead of () to avoid deprecation warning
- Fix Classpaths.publishTask to use variant without delivery key (deprecated since 1.1.1)
- Add scala.sys.process._ import for shell command execution
- Fix publish/publishLocal to use {} instead of ()
- Remove problematic resolvers setting that caused task/setting dependency issues
- Use IvyActions.publish directly instead of deprecated Classpaths.publishTask
- Fix ModuleID.copy to use withRevision
- Fix Artifact.copy to use withExtension
- Use computed status value instead of status key

Build now compiles successfully with sbt 1.10.7.

**Problem/Solution**
This is a follow up to launcher package migrating to sbt 1.x.
This joins the launcher package into the main build.

[1.x] bport: Upgrade launcher-package to sbt 1.10.7

- Change from prepend to append for machine/dist sbtopts
- Change project .sbtopts from prepend to append so it appears last
- Project-level .sbtopts now correctly overrides machine-wide configs
- Add integration tests to verify sbtopts priority order
- Extend testOutput to support dist and machine sbtopts testing
- Copy staging directory to temp location to avoid modifying staging dir

Fixes #7497

Only recombine split -- arguments after new/init command.

Fixes #7507

Previously, passing JVM options like -Xmx1G directly on the command
line would result in an error:

  sbt -v -Xmx1G
  [error] Expected ';'
  [error] -Xmx1G
  [error]       ^

This was because -X options were being passed to sbt as commands
instead of being recognized as JVM arguments.

Changes:
- Added handling for -X options in sbt.bat to pass them to the JVM
- Updated help text to document this feature
- Added integration tests for the new functionality

[1.x] Backport runner script changes

* create `project` directory if extra sbt files are added to the meta-build #8570

[1.x] fix: Invalidate update cache across commands when dependencies change

**Problem**
We enforce same-version policy for scala-reflect in Scala 2.13.
However due to sandwich dependency, the graph can bump
scala-library to 3.8.1, which is missing scala-reflect counterpart.

**Solution**
Drop the same-version policy.
