chore: Config Updates ( TOML / JSON / YAML )

[lxfontes]

More config formats

This PR aligns wash config with its underlying crate: figment

With these changes, wash config:

• Can be expressed as JSON / YAML / TOML
• Match file extensions ( .json, .yaml | .yml, .toml )

CLI Context ( Execution Directory )

Instead of requiring each wash command to manage project path locations, we now centralize all project path operations in global arguments and follow similar gnutools expectations.

We take the current directory into account and try to find the .wash directory walking back the directory tree.
If we can't find the project root, we use the current directory.

We also expose a -C flag where users can force a project path. This is useful in CI environments & situations where users cant change directories prior calling wash.

Auto Update

Auto update file management was ☠️ . It would never expire the local cache, meaning you'd never be able to upgrade or refresh the cache ( as we don't provide a cache clear option ).

This PR makes is so the local cache for release-list is refreshed at most once in 24 hours.

Test fixes

We were changing the current directory in many parallel tests. This could cause tests to override each others files & fail.
integration_wit.rs now executes tests in sequence.
