CLAUDE.md: pull at session start, remind to commit and push

Adds an 'Every session' section: git pull --ff-only before the first request, and a one-line reminder when work is left uncommitted or unpushed. Moves the Gitea details into that section.

+## Every session: stay in sync with Gitea
+
+This repo is backed up to `http://10.3.8.90:3000/chris/AV-Watch` (private, branch
+`main`). The Git login is in Windows Credential Manager, not in this repo.
+
+1. **Pull at the start.** Before starting on the first request of every session,
+   pull in the repo root (`C:\Users\Live Stream\Desktop\Claude\avwatch`):
+
+   ```powershell
+   # 'never' makes a bad token fail fast instead of opening a login window
+   $env:GCM_INTERACTIVE = 'never'; git pull --ff-only
+   ```
+
+   Report the result in one line, then carry on with the request. If the pull
+   fails (server unreachable, local changes in the way, history diverged), say
+   why in that line and carry on. Don't stash, reset, rebase or merge to get past
+   it unless asked. If `git` isn't found, use `C:\Program Files\Git\cmd\git.exe`.
+
+2. **Remind before finishing.** When you finish a piece of work and `git status`
+   shows uncommitted changes or unpushed commits, end your reply with a one-line
+   reminder of what isn't on Gitea yet and offer to commit and push. Do the same
+   when the user says they're wrapping up. Only commit or push when asked, and
+   don't repeat the reminder if nothing has changed since the last one.
