Update dependency dotenv to v16.6.1

| datasource | package | from   | to     |
| ---------- | ------- | ------ | ------ |
| npm        | dotenv  | 16.5.0 | 16.6.1 |


## [v16.6.1](https://github.com/motdotla/dotenv/blob/HEAD/CHANGELOG.md#1661-2025-06-27)

##### Changed

- Default `quiet` to true – hiding the runtime log message ([#874](motdotla/dotenv#874))
- NOTICE: 17.0.0 will be released with quiet defaulting to false. Use `config({ quiet: true })` to suppress.
- And check out the new [dotenvx](https://github.com/dotenvx/dotenvx). As coding workflows evolve and agents increasingly handle secrets, encrypted .env files offer a much safer way to deploy both agents and code together with secure secrets. Simply switch `require('dotenv').config()` for `require('@dotenvx/dotenvx').config()`.


## [v16.6.0](https://github.com/motdotla/dotenv/blob/HEAD/CHANGELOG.md#1660-2025-06-26)

##### Added

- Default log helpful message `[dotenv@16.6.0] injecting env (1) from .env` ([#870](motdotla/dotenv#870))
- Use `{ quiet: true }` to suppress
- Aligns dotenv more closely with [dotenvx](https://github.com/dotenvx/dotenvx).
