…vars Writes CLICKHOUSE_HOST, CLICKHOUSE_PORT, CLICKHOUSE_HTTP_PORT, CLICKHOUSE_USER, CLICKHOUSE_PASSWORD, and CLICKHOUSE_DATABASE into a .env file from a running server's connection details. Supports --name to target a specific server and --local to write to .env.local instead. If the file already exists, CLICKHOUSE_* vars are replaced in-place rather than appending duplicates.

Two fixes to `local server dotenv`: 1. Only write vars we actually know from server metadata (host, ports). User, password, and database are no longer hard-coded — instead they are opt-in via --user, --password, --database flags. This prevents overwriting a working .env with incorrect defaults. 2. The dotenv updater now handles common variants: `export` prefix and whitespace around `=`. Previously `export CLICKHOUSE_HOST=x` would survive replacement and produce a duplicate line.

If the existing .env file uses `export CLICKHOUSE_X=val`, the replacement now keeps the `export` prefix instead of silently dropping it. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Values like `my secret#123` are now written as `"my secret#123"`. Embedded double quotes, backslashes, and newlines are escaped. Plain alphanumeric values remain unquoted. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
