chore: tooling improvements

- Add cargo-binutils to mise.toml (needed for `just size`)
- Remove jj from mise.toml (optional, not a build dependency)
- Silence `mise install` output when tools are current (--quiet)
- Add `just outdated` recipe with embassy-executor exclusion
  (esp-rtos 0.2 pins embassy-executor ^0.9; 0.10 renamed arch-*
  features to platform-*, which crashes cargo-outdated)
