fix: Maven Toolchains grows unexpectedly (#534)
* fix: Maven Toolchains grows unexpectedly On self-hosted runners toolchains.xml may survive multiple runs and unexpectedly grow as a result of the toolchains setup simply appending the JDK definition even if one with the same `type` and `provides.id` already exists. Restructuring the parsing step and filtering the potentially existing list of toolchain definitions prevents this and also fixes toolchain.xml files that already contain duplicates. Fixes #530 * fix: guard toolchain dedup and preserve existing root attributes Address reviewer feedback on the Maven toolchains dedup logic: - Treat jdk toolchains without a string `provides.id` as non-deduplicatable and use optional access when comparing ids, so partially-formed or nonstandard toolchains.xml files no longer crash setup. - Preserve the existing `<toolchains>` root attributes (xmlns, schemaLocation, …) when present, falling back to the 1.1.0 defaults only for attributes the existing file is missing. This avoids silently rewriting user-managed metadata or changing the effective namespace. Adds tests covering custom root attributes and id-less jdk toolchains, and rebuilds dist/.
