Improve memory inspection presentation

Reformat /memory into the same structured console style as the other polished commands and enumerate discovered instruction files in ancestry order with line counts and previews. This makes repo instruction memory easier to inspect without changing the underlying discovery behavior.

Constraint: Memory reporting must reflect only the instruction files discovered from current directory ancestry
Rejected: Add memory editing commands in the same slice | presentation polish was a cleaner, lower-risk improvement to ship first
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep instruction-file ordering stable so ancestry-based memory debugging stays predictable
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual inspection of repos with many nested CLAUDE files
