Name sessions from the CLI, rename them in the app, and fix the team audit key

[Alexgodoroja]

Naming sessions

• shell --name <name> <command> labels a session as it starts. The name is published to the account, kept in the local record, and shown on the start card, in shell list, and in the web app. A persistent session that restarts without --name keeps the name it has, so a rename made in the browser is no longer undone on every restart.
• shell ls lists the sessions in your account from every linked machine, which shell list cannot: it only knows this one. It shows name, status, uptime, machine, and command. Ended sessions are counted and hidden until --all; --json prints the complete records and never a password. It needs a linked machine, and to share a program called ls, put -- first.
• Renaming from the session page: the pencil beside the name opens it for editing, and a blank name falls back to the command. The owner, an assignee, or a team admin may rename, which is the rule the service applies too.

The terminal

The bordered dark panel is gone. The pane is transparent, the emulator's canvas is clear, and its palette follows the app's light and dark themes, including a change while a session is open. The standard ANSI colors assume a dark background, so the light palette darkens each one to the app's ink weights rather than leaving them illegible on paper. The renderer choice moves out of the tab strip into a tab hanging from the tab line over the terminal's top-right corner, where it covers padding rather than text.

The team audit key

Every member of a team can now read the audit log without pasting anything.

A member who opened the copy of the key a teammate sealed for them re-sealed it to themselves by deleting the stored copy and adding it back. The service takes copies only from a member who holds one, so the second step was refused and the error swallowed. On the next check that member held nothing, the log went back to sealed, and they never passed the key on; only the key's maker kept a working copy. PUT /api/team-key/share now replaces a member's own copy in one step, so the key reaches everyone and an unlocked vault opens the log by itself.

The vault on the Account page lists teammates still waiting for a copy, and asks before sealing the key to a teammate whose vault key has changed, since sealing to a swapped key would hand over the whole log. The audit log says when a locked vault, or no vault, is what stands between the reader and the log, and offers to unlock it there.

Not starting a daemon from a test binary

An ordinary command brings the machine daemon up by running this executable again with daemon. Under go test that executable is the test binary, which runs the whole suite instead, whose tests start daemons of their own. A test that reached run() without credentials of its own read the developer's real ones and set that going: hundreds of processes and a machine too busy to type into. ensureDaemon and restartDaemon now refuse to launch a .test executable, and the package's TestMain exits at once when the test binary is started as a subcommand and points credentials at a file that does not exist.

Checks

go test ./..., npm run typecheck, the app's 918 tests, the root suite, and the landing/formula checks all pass. The UI was driven in a browser against a local relay with real shell sessions: naming from the CLI, renaming from the session page, the terminal in light mode with a full ANSI color sample, and the audit and account pages.
