v0.7.0

Twenty-three commits since v0.6.0, still in the distilled spirit of the project:

• Thinking models show their work (745ff65): deepseek-reasoner, kimi-k2-thinking and friends stream reasoning_content next to the answer. CoreCoder now surfaces it as it arrives instead of dropping it, and keeps it out of the reply and the history so context stays clean.
• Streams retry wholesale, not just at connect (745ff65): a stream that died mid-drain used to kill the whole round; only the connect was retried. The drain is now inside the same backoff, so a dropped connection or a 5xx partway through re-issues the request. A 4xx still raises immediately.
• Windows is a first-class shell citizen (8a44515, a18a4ac): command spawns route through Git Bash and drive-letter paths are posixified before they reach it. The Windows CI lanes are green again, and lint agrees.
• cwd tracking got honest (b96a3b7, 2c49e74, 9c7fc18, ea46fd8): the shell watcher follows cd chains across semicolons, never inside subshells, quote-aware, with backslashes verbatim and Python 3.10 intact. Parallel bash calls share one cwd, and same-file edits serialize instead of racing.
• Token estimates tier by content type (d74fdbf): code, prose and markup no longer price like the same text.
• Direct OpenAI-path param adaptation (8990203, 66804de): rejected sampling params are adapted rather than fatal, and the tests track openai 3.14's httpx2 switch.
• /undo recreates a deleted parent tree (27977ee), with a hooks and checkpoints audit behind it.
• Reading track: essay 08 on the v0.6.0 extensibility trio is live in both languages, the hooks section grew two copy-pasteable cookbook examples, and the first-screen demo shows plan mode and hooks as they are now.

Full essay series and the code map are in the README. As always: readable end to end, hackable, and the gaps are still the point.
