l0ng-ai bf2427bd3a feat(java): selectable Java formatting profiles (#680)
Java formatting comes from jdtls' Eclipse formatter, whose defaults differ from the IntelliJ IDEA code style. Settings › Editor › Code Style › Java now offers a formatting profile: Default (unchanged), IntelliJ IDEA, or a custom Eclipse formatter XML (absolute or project-relative path).

The IntelliJ IDEA profile is a bundled Eclipse formatter XML that follows IDEA's default Java code style item by item (indents, aligned multi-line parameters, annotation placement, else/catch/finally on the same line, array initializers, lambdas, blank lines, comments not reflowed). Manual line breaks are kept; lines longer than 120 columns wrap where necessary, which differs from IDEA's default of not wrapping. The profile reaches a running jdtls through didChangeConfiguration without a restart; an unreadable custom file shows a warning and leaves code intelligence running. Code style changes reconfigure language servers without scheduling Kotlin bridge builds.

Also drops two catalog entries whose texts are no longer used.
