Release 0.4.0

[igray]

Version bump for the release following #6.

Why 0.4.0 and not 0.3.2

#6 narrowed the ruby-lsp dependency from ~> 0.17, >= 0.12.0 to ~> 0.26, dropping support for nine minor versions of the host LSP. Anyone pinned to ruby-lsp 0.17–0.25 cannot take this upgrade. On a 0.x gem the minor slot is where breaking changes go, so a patch bump would misrepresent it.

Two smaller compatibility notes, neither of which drives the decision on its own:

• required_ruby_version went >= 2.5.0 → >= 3.0.0. This is mostly a correction rather than a real narrowing — ruby-lsp 0.17 already required Ruby >= 3.0, so 2.5 was never actually viable. It is now enforced at install time.
• sorbet-runtime is no longer a dependency. Not a break for this gem's own API, but anyone who was implicitly relying on ruby-lsp-reek to pull sorbet-runtime into their bundle will no longer get it.

The two methods removed from Runner (build_examiner, warning_to_diagnostic) were both private, so they are not part of the public surface.

Verification

Built the 0.4.0 gem and inspected the artifact:

version: 0.4.0
ruby: >= 3.0.0
runtime: reek ~> 6.0
runtime: ruby-lsp ~> 0.26
files: lib/ruby_lsp/reek/addon.rb, lib/ruby_lsp/reek/diagnostic.rb,
       lib/ruby_lsp/reek/runner.rb, lib/ruby_lsp/reek/version.rb

No sorbet-runtime, and diagnostic.rb is packaged. Suite is green: 4 runs, 14 assertions, 0 failures, and rake code_analysis reports 0 total warnings.
