ci: put CI keychain first in codesign search list

codesign resolves signing identities through the user keychain search
list (first match wins) and ignores --keychain for the lookup. This
runner hosts another project (Sybil-2) whose keychain holds the same
Apple Distribution identity, so if that keychain is locked and appears
earlier in the search list, codesign fails with errSecInternalComponent
no matter how correctly our own keychain is set up. Prepend the fresh
CI keychain to the search list for the build and always delete it
afterward, which restores the original list.

+# Attractor
+
+Attractor is a web browser for iOS and macOS prioritizing security and aggresive content filtering, and some nifty useful features. 
+
+![](Screenshots/main.png)
+
+## Security Modes
+
+Attractor aggresively filters unwanted web content and prevents arbitrary code execution (JavaScript) by default. I created a special browser for this purpose. Philosophically speaking, I believe the web should primarily be used as a document viewer (as originally intended by [Tim Berners-Lee](https://en.wikipedia.org/wiki/World_wide_web)). Interactive web applications are fine, but the *default* mode should be document viewing, which is why this security model exists. 
+
+Attractor operates in five "security modes":
+1. **Alpha** (Default) All JavaScript is blocked, as well as web fonts and iframes. 
+2. **Bravo** Only embedded scripts are allowed. This means any JavaScript enclosed in `<script>` tags. Often this is enough to allow form validation to occur without issue. 
+3. **Charlie** Allows external JavaScript, but only from the same security origin. Meaning, if browsing `buzzert.net`, only external scripts from the domain `buzzert.net` (or subdomains) are allowed to execute. 
+4. **Delta** Allows external JavaScript, but only from a curated list of common CDNs. 
+5. **Echo** All scripts are allowed. 
+   
+## Other features
+
+- Dark mode (a very good one that uses low-level stylesheet injection to prevent flicker) 
+- Tab syncing
+- Share via Email
+- Reader Mode
+- Arbitrary zoom scale
+- User-defined scripts and stylesheets via UI
+- Custom redirect rules
+- Catalyst and iPadOS support
+
+## Deployment
+
+TestFlight deployment is handled by Fastlane and the Gitea workflow at `.gitea/workflows/testflight.yml`.
+
+Required Gitea secrets match the local `.env.example`: `APP_STORE_CONNECT_KEY_ID`, `APP_STORE_CONNECT_ISSUER_ID`, `APP_STORE_CONNECT_KEY_CONTENT`, `MATCH_GIT_URL`, `MATCH_PASSWORD`, and `MATCH_GIT_BASIC_AUTHORIZATION`.
+
+Push a tag like `release/ios/v4.2` or `Attractor-4.2` to build and upload to TestFlight. To prepare signing assets locally, run `bundle exec fastlane ios setup_signing`; to upload manually, run `bundle exec fastlane ios beta`.
