Feature request: add support for Bazel/Bazelisk

Summary

Bazel (and Bazelisk) builds can be extremely verbose and would benefit from RTK filtering for Java/JVM developers using Bazel as their build system.

Why Bazel needs a dedicated Rust module (not just TOML)

Bazel sends most of its output (progress, errors, summaries) to stderr, not stdout. TOML filters only capture stdout, so they miss ~90% of Bazel's output. A dedicated Rust module using runner::run_filtered can capture and filter both streams.

Commands that should be supported

• bazel build / bazelisk build — strip [X / Y] progress lines, INFO: noise, Loading:, Analyzing:, repo cache info; keep ERROR: and build result
• bazel test / bazelisk test — show only PASSED/FAILED per target and summary; strip progress noise
• bazel query / cquery / aquery — strip INFO: and Loading: lines, keep target labels
• bazel run — same filtering as build
• bazel clean — compact output

Estimated savings

Operation	Raw output	Filtered	Savings
bazel build (success)	~30 lines	1 line	~95%
bazel build (failure)	~30 lines	3-5 lines (errors only)	~85%
bazel test (all pass)	~20 lines	1 line	~95%
bazel query //...	~10+ INFO lines + targets	targets only	~50-80%

Reference implementation

I have a working implementation in my fork: https://github.com/tructxn/rtk/commit/58fb4ef

Key files:

• src/cmds/jvm/bazel_cmd.rs — dedicated Rust module with build/test/query/run/clean filters (13 unit tests)
• src/cmds/jvm/mod.rs — JVM ecosystem module
• src/filters/bazel-build.toml, bazel-test.toml, bazel-query.toml — TOML fallback filters for hook rewrite path
• src/main.rs — Commands::Bazel with BazelCommands subcommands

All 1363 tests pass. Regex matches both bazel and bazelisk via ^bazel(isk)?.
