Bumps to v0.2. Resolves the open questions and design gaps flagged during
review before implementation starts:
- Spells out the supervisor detach/re-exec mechanism (§3), mirroring how
vmic solves the same one-shot-CLI-can't-host-a-daemon problem.
- Forces BatchMode/ExitOnForwardFailure/ConnectTimeout on every ssh
invocation so headless failures surface instead of hanging on a TTY
prompt (§3.1).
- Adds backoff + stderr-based fatal/transient failure classification so
reconnect doesn't retry forever against a permanently broken profile
(§4).
- Collapses the Instance `state` enum to up/reconnecting/error, with
"no instance file" as the sole meaning of closed, removing the prior
ambiguity around close vs. crash vs. down (§2.2, §3).
- Fixes --via's conflicting comma-list-vs-repeated-flag examples by
committing to a straight ssh -J passthrough grammar (§3.1/§5.1).
- Resolves the edit --restart open question: no --restart, stays explicit.
- Simplifies exit codes to 0/1/2 (was a 6-code table with its own TODO).
- Adds a lock file for concurrent-open safety and a log rotation policy.
- Calls out reboot/logout survival as an explicit v0.1 non-goal, with
`open --all` as the only hook left for external autostart wiring (§8).
