chore: format

* feat: allow replacing of blade template namespaces

* wip: add `prependNamespace` support

* test: add replace namespace test

* Apply fixes from StyleCI

[ci skip] [skip ci]

* fix: add missing property

* fix: add view namespaces before resolving

Allows `replaceNamespace()` extender to actually remove old routes.

* test: make replace test ensure that replaced view does not exist

* docs: update docblock

* Apply fixes from StyleCI

[ci skip] [skip ci]

* fix: missing `\` before class

* fix: change test view namespace

* chore: simplify test

* Remove replace namespace code

We only really need prepend.
