* fix: Stop the status refresh loop and the double project open at startup
Every status rewrote .git/index, even with nothing to persist: gix's
`write_changes` writes an empty change set too. The watcher reports
.git/index writes as VCS changes, so each status triggered the next one,
together with an ahead/behind walk. On a repository with a long history
(freqtrade, 33k commits behind upstream) that kept a core busy for as long
as the project was open. Write back only when `has_changes()`.
A project passed on the command line was opened twice: the launch and the
"reopen last project" restore ran concurrently, and the restore checked
for an open project before the launch had finished. The second open found
the index cache locked and indexed in memory only; with a different last
project, the window ended up on whichever finished last. The restore now
waits for the startup launch.
* fix(lsp): Run jdtls on the Java version its bundles need
jdtls's launcher checks for Java 21, and so did JDTLS_MIN_JAVA, but the
Eclipse platform a release ships moves on: 1.63 bundles
org.eclipse.core.filesystem with JavaSE-25, so on a JDK 21 the server died
resolving its bundles ("jdtls is not ready (Crashed)") and the error told
users to install the 21 they already had.
Read the requirement from the installed jdtls instead: the highest osgi.ee
capability / Bundle-RequiredExecutionEnvironment among its plugins'
manifests (cached per install), never below 21. The runtime choice, the
rescan while no JDK fits and the "needs JDK N" message use it.
