codewhale-cli 0.10.0

//! `codewhale --resume <id>`, `--resume=<id>`, `-r <id>` and `--session-id <id>`
//! are root dispatcher flags (the operations runbook advertises the first)
//! that forward to the in-process TUI's `--resume`. They used to be swallowed
//! by the trailing prompt positional and forwarded as `--prompt "--resume
//! <id>"`, which the TUI's own parser rejected (`error: unexpected argument
//! '--resume <id>' found`, exit 2). A non-TTY launch must now get past
//! argument parsing and fail only on the interactive-terminal contract, and
//! must not create session state under a sealed HOME on the way out.
//! Fresh-session and mouse flags exercise the same boundary: an unrecognized
//! `--fresh` previously swallowed the remaining flags as one prompt value.
