refactor(jvm): merge java module into jvm

Upstream introduced src/cmds/jvm/ (gradlew). Consolidate the Maven filter
(mvn_cmd, pom_groupid, stack_trace, surefire_reports) under the same jvm/
umbrella so the module layout matches upstream.

- move src/cmds/java/* -> src/cmds/jvm/*
- crate::cmds::java:: -> crate::cmds::jvm::
- rename insta snapshots __java__ -> __jvm__ and fix source: headers
- drop `pub mod java;` (jvm/mod.rs automod already covers the dir)
- docs: src/cmds README, jvm README title + gradlew note, module map

 - Routing via Clap sub-enum with `#[command(external_subcommand)] Other` for unknown goals; compile-like and checkstyle goals received as `Other` are auto-re-dispatched by `route_goal` to the right filter
 - **Multi-goal chains** (≥2 goals, e.g. `mvn clean test-compile checkstyle:check`, `mvn clean verify`, `mvn clean install`): a signal-aware filter splits output by Maven plugin boundary markers, runs each segment group through its matching single-goal filter, and always preserves the BUILD signal — all `[ERROR]` lines, `BUILD SUCCESS`/`BUILD FAILURE` + `Total time`, per-module test counts, checkstyle violation counts, and (on failure) the Reactor Summary failing module. `-q`/`--quiet` is automatically stripped in multi-goal mode so rtk receives full output and does the compression itself. When the chain includes `test`/`verify`/`install`, surefire/failsafe XML enrichment applies exactly as for single-goal `verify`.
