chore(ci): Split monolithic ci.yml into separate workflow files

Split the CI workflow into focused files with appropriate path filters:
- ci.yml: Core lint, test, and build (paths-ignore website/, browser/)
- ci-website.yml: Website client/server lint and bundle (paths: website/**)
- ci-browser.yml: Browser extension lint and test (paths: browser/**)
- ci-quality.yml: actionlint, zizmor, typos (broad paths-ignore)

This reduces unnecessary job execution by ~40 jobs when only a subset
of the codebase changes, and improves workflow readability.
