build(deps): bump zeitwerk from 2.7.3 to 2.8.0

[dependabot]

Bumps zeitwerk from 2.7.3 to 2.8.0.

Changelog

Sourced from zeitwerk's changelog.

2.8.0 (18 May 2026)

• Adds support for namespace files, nsfiles for short.

  If a loader has an nsfile configured (nil by default):

  loader.nsfile = 'ns.rb' # must be set before setup

  explicit namespaces can be defined by such special file inside their directories:

  my_component/ns.rb     # MyComponent
  my_component/widget.rb # MyComponent::Widget
  

  This may be handy for self-contained units for which a my_component.rb file in the parent directory would feel unnatural.

  If an nsfile is set, you can still define explicit namespaces as always. Both styles can coexist in the project. However, it is an error condition to try to define the same namespace using both conventions.

  For further details, please check the documentation for nsfiles.

• When a file is shadowed because the constant path it maps to already exists, the location of said constant is included in the log message.

2.7.5 (19 Feb 2026)

• If available, tree traversal is based on Dir.scan, which saves syscalls in common platforms. This method is a recent addition to Ruby contributed by @​byroot, so you need to be on Ruby master to leverage this for now.

• Tree traversal is a tad more performant, regardless of the previous point. Gains are marginal when eager loading, because it is dominated by loading the code, but Zeitwerk::Loader#all_expected_cpaths was 14% faster in some benchmarks, for example.

• README.md documents how to collect autoloaded constants using an on_load callback.

• Internal maintenance.

2.7.4 (16 Dec 2025)

• Loaders have to manage disjoint source trees. Therefore, when a root directory is configured Zeitwerk ensures it is not already managed by some other loader. The performance of this validation has been improved.

  Thanks to @​ngan for sharing some benchmarks that led to revise this logic.
