Make local sandbox execution direct by removing the public worktree mode and in-place controls from CLI, config, run state, API surfaces, docs, and UI. Keep worktree support only for internal parallel-node isolation.
ULID-derived sandbox names like fabro-01KQR3V9D4VPFFWMNTVH09J48G tripped
the entropy detector and rendered as REDACTED in CLI run output.

Remove redundant as_str/from helper methods on provider, reasoning, model-test, safe URL, and interview types. Migrate call sites to Display, IntoStaticStr, and FromStr while keeping wire-format coverage in tests.
Move secret redaction and DisplaySafeUrl into fabro-redact so credential handling has a narrow ownership boundary. Update direct consumers and docs to depend on fabro_redact instead of fabro_util::redact.
