Fixes #137

What and why

From discussion #120: Herd's herd open and herd db. Flock only had flock worktree open (worktrees only) and no database command.

• flock open [site|dir] — opens a site in the browser: the current one, by name, or by directory. Uses the URL the daemon serves, or the site's own when the daemon is stopped.
• flock db [site|dir] — opens the database its .env names (PostgreSQL, MySQL, MariaDB, SQLite, MongoDB) in the client registered for postgres:///mysql:// links, else an installed TablePlus, TablePro, DataGrip or DBeaver. --url prints driver, host, database, user and URL instead.
• The password only reaches the client; everything printed is masked.
• Only these two commands accept a directory, so a path can't change another command's target.

How I tested it

Both commands against a throwaway FLOCK_HOME: open by directory, db --url for PostgreSQL and SQLite, --client with and without %s, and the error paths (unknown site, no .env, unknown driver). Unit tests cover the driver URLs, masking, the client splitter and site/directory resolution. go test -race, go vet, gofmt and builds for linux/darwin/windows are clean.

Not tested on macOS or Windows.
