feat(cross-cutting): added shell minimizer planning from AST command parsing

- Added AST-based minimizer planning with brush-parser to classify commands before minimization.
- Added original text capture and byte-metric `minimized` telemetry to shell execution results.
- Added minimizer configuration controls, including trust-gated loading via `settingsHash` and limits.
- Added `onMinimizedSave` callback wiring to persist minimized outputs and annotate Bash sinks with artifact IDs.
