feat(automation): one-command updater for the deployed PR-review watcher

Browse source 
update-pr-review-watcher.sh refreshes the deployed script from the repo via a
dedicated self-update checkout (~/pr-review-watcher/.src) that never races the
issue watcher's work clone. Reads the live config for auth, never clobbers the
config (real token), and self-updates. Optional ref arg for pre-merge testing.

- A Windows `.ps1` port is not provided yet (pms1 is the sole worker); port it from
`claude-issue-watcher.ps1` only if you need a failover.
**Updating the deployed copy:** `update-pr-review-watcher.sh` refreshes the watcher
script in one command, from a dedicated self-update checkout (`~/pr-review-watcher/.src`)
that never races the issue watcher's clone. Copy it once, then:
```sh
cp automation/update-pr-review-watcher.sh ~/pr-review-watcher/ # one-time
~/pr-review-watcher/update-pr-review-watcher.sh # pull from master
~/pr-review-watcher/update-pr-review-watcher.sh some/branch # or a branch (pre-merge testing)
```
It reads the live config for the token/URL, never clobbers the config, and self-updates.
## Test database (for autofix verification)
So the fix stage can verify against realistic data without touching production:
