refactor(cli): replace verbose/quiet bool pairs with Verbosity enum

[bug-ops]

Summary

• exarch-cli's output-formatter and progress-selection code took separate verbose: bool, quiet: bool parameters, allowing the nonsensical verbose: true, quiet: true state and, in extract, resolving it inconsistently between the formatter (quiet-wins) and the progress reporter (verbose-wins).
• output::create_formatter, HumanFormatter::new, HumanFormatter::with_writers, commands::extract::execute, and commands::create::execute now take a single output::Verbosity (Quiet | Normal | Verbose) instead, resolved once via impl From<&cli::Cli> for Verbosity in main.rs and threaded through every call site.
• --verbose/--quiet remain independent clap flags with conflicts_with on --quiet; that check only rejects the pair when both land in the same ArgMatches level (e.g. exarch list --verbose --quiet), so a split-level combination such as exarch --verbose extract archive.tar.gz out --quiet still parses with both true — Verbosity::from_flags now resolves that case deterministically to Quiet.

Behavior change

extract's progress reporter previously selected VerboseProgress whenever --verbose was passed, even together with --quiet (verbose-wins), while the formatter suppressed the summary (quiet-wins) — so --verbose extract ... --quiet printed per-entry progress lines but no summary. Both now consistently resolve to Quiet (no progress output, no summary) through the same Verbosity value.

Closes #550

Test plan

• cargo +nightly fmt --all -- --check
• cargo clippy --workspace --all-targets --all-features -- -D warnings
• cargo nextest run --workspace --all-features --exclude exarch-python --exclude exarch-node (1234/1234)
• cargo test --doc --workspace --all-features --exclude exarch-python --exclude exarch-node (117/117)
• RUSTFLAGS="-D warnings" RUSTDOCFLAGS="--deny rustdoc::broken_intra_doc_links" cargo doc --no-deps --all-features --workspace
• Added unit tests covering all four Verbosity::from_flags combinations, including the previously-nonsensical (true, true) case
• Added a regression test parsing --verbose extract ... --quiet via Cli::parse_from to verify split-ArgMatches-level resolution
• Live-verified with the built binary that exarch --verbose extract t.tar.gz out --quiet now produces no progress output and no summary, consistent with the formatter
