Summary

• replace the implicit command facade with explicit apply, dry-run, check providers, and list command families
• add typed target, profile, and exact job selectors, including minimal provider closure for selected package jobs
• add stable TSV listings for targets, profiles, and jobs so external tools such as fzf can compose an interactive workflow without becoming part of dot
• separate complete static configuration validation from selected runtime resolution, and reuse one ExecutionPlan for apply and dry-run
• document the new selection model and CLI contracts

Why

Dot needs execution granularity from an entire target/profile down to individual package, action, or link jobs. The previous CLI and manifest path could not expose that model cleanly or safely compose with external selectors.

This change makes selection explicit while preserving dot's core boundary: the complete TOML is validated statically, only selected jobs are resolved at runtime, and dot remains a bootstrap executor rather than a package manager or interactive DSL.

User impact

This intentionally removes the legacy implicit apply and global dry-run syntax. Users now select an explicit operation and may repeat --job for exact execution. The new list ... commands emit headerless stable TSV suitable for shell pipelines and fzf.
