fix(stream): passthrough watch commands

[nkootstra]

Summary

Fixes watch/dev-style commands that previously looked like they were streaming but still buffered through RTK filtering paths until the child process exited.

This routes known long-running invocations through passthrough execution so stdout/stderr stay attached to the terminal, while still keeping normal filtered commands on the existing buffered/streaming pipeline. It also updates unsupported go and dotnet passthrough paths to actually stream instead of capturing via .output().

Changes

• Detect watch/dev/follow/codegen-style invocations centrally before applying filtered execution.
• Preserve gh pr checks --watch detection when extra args are present.
• Stream interactive Playwright, unsupported Go, and unsupported Dotnet passthrough routes instead of buffering them.
• Include small clippy cleanups required by the current develop branch.

Verification

• smll cargo fmt --all
• smll cargo clippy --all-targets
• smll cargo test --all (1691p 0f)

Closes #1545

Summary

Fixes watch/dev-style commands (e.g. --watch, dev, serve, codegen) that were being buffered through RTK's filtered execution pipeline instead of streaming directly to the terminal. Adds centralized detection of long-running/streaming invocations in the runner module and routes them through passthrough execution, while also converting unsupported Go and Dotnet passthrough paths from buffered capture to proper streaming.
