BREAKING CHANGE: Remove the deprecated execute on mount functionality, found in hooks.

… functions (#336)

This PR introduces a callback in both action and hook contexts, called
`onNavigation`, that is triggered when the user uses a function imported
from `next/navigation` inside the action body.

…on, throw them instead (#337)

This PR removes the shaper `handleBindArgsValidationErrorsShape` util
function, and also removes `bindArgsValidationErrors` from the result.
Instead, if bound args validation errors occur, throw them on the
server, using a new `ActionBindArgsValidationError` error class.

Code in this PR brings back the always defined safe action result, so
users can destructure the result object, and access its optional
properties directly. This is because `next/navigation` functions don't
trigger an `undefined` result anymore, so everything works as expected
now.

The code in this PR renames the `schema` instance method to
`inputSchema`.
Since introducing output validation with the `outputSchema` method, I
have considered renaming `schema` to `inputSchema` to make its purpose
clearer.

Note that the `schema` method will remain as an alias for `inputSchema`,
but will be removed in a future release.

Code in this PR simplifies internal library code by a lot.

If a metadata schema is provided via `defineMetadataSchema` init function, and the `metadata` method
is not used before `action`/`stateAction` method, now an error will inform the user that the type is
incomplete.

…wValidationErrors` (#346)

Code in this PR adds the ability to override the validation error
message, when the `throwValidationErrors` option is used at the action
level, using an optional async function called `overrideErrorMessage`,
that returns the overridden error message, instead of the default one.
