Agent Console: äldre versioner att ladda ner

> **License change:** starting with this release Agent Console is **AGPL-3.0-only** (v0.75.0 and earlier remain MIT, irrevocably). If you just *use* the app — personally or at your company — **nothing changes for you**：no obligations, no disclosure, your code stays yours. The license only bites if you distribute or network-serve a modified build of the app itself. Details: [README → "Using Agent Console at work"](https://github.com/cyl-castillo/agent-console#using-agent-console-at-work).

## Highlights

• **Rewind to a turn — files AND conversation together** (#174). Every closed turn in the proof timeline gains *↶ rewind to this turn*：the working tree is restored to that turn's snapshot (with a backup taken first, so the rewind itself is undoable) and a new session opens with Claude's memory rewound to that same point, via a non-destructive fork of the session transcript. The original session and transcript stay untouched as history, and the rewind lands in the evidence ledger as an auditable event. Claude-only for now; if the fork isn't possible, files are still restored and the app says so instead of pretending.
• **Failed turns now close, and say why** (#169). When the API refuses a turn (expired login, billing, org policy), Claude fires `StopFailure` instead of `Stop` — previously that turn hung open forever. Now it closes through the same path as a normal turn (diff included), the timeline renders it as failed with the reason, and the error toast points at "Fix Claude login" only when logging in again would actually help.
• **Links in the terminal actually open** (#170). OSC 8 hyperlinks (used by Claude for docs/PR links, and by Codex 0.150+ for markdown labels) now open in your real browser instead of dying in a blocked `window.open`. http(s) only, destination shown on hover.
• **The model pill stops lying** (#172). `PostModelSwitch` (Claude 2.1.251+) reports the model that's *actually* running — so a `/model` typed in the terminal, or Claude falling back on its own, no longer leaves the pill stale (and no longer drags the next `--resume` back to the wrong model).
• **README got a face** (#166, #167, #168)：real screenshots, refreshed landing, and the getting-started pill no longer covers panel buttons.

## Notes

• Windows binaries remain unsigned (work in progress — SignPath/Certum). winget publish for this version is pending a token rotation; AppImage self-updates in place, .deb/.rpm show the manual-download banner as usual.
