[Release] v1.6.0 - #501

Release

Bumps RubyUI::VERSION to 1.6.0. Minor per SemVer — a new component and new component options landed since v1.5.0, no breaking changes.

• gem/lib/ruby_ui.rb → 1.6.0
• gem/Gemfile.lock + docs/Gemfile.lock regenerated (both now read ruby_ui (1.6.0); version line is the only change in each)
• docs/app/views/pages/home.rb — hero badge copy updated to the headline features. The header version badge reads RubyUI::VERSION and needs no edit.
• mcp/data/registry.json — rebuilt with cd mcp && bundle exec rake mcp:build

Highlights since v1.5.0

New component

• InputOtp ([Feature] Add InputOtp component #456)

Component improvements

• Combobox: configurable popover placement + minPopoverWidth ([Improvement] Combobox: configurable popover placement #480), CheckboxGroup reuse for required ComboboxCheckbox (feat(combobox): reuse CheckboxGroup for required ComboboxCheckbox #479), single chevron-down icon in trigger (feat(combobox): use single chevron-down icon in ComboboxTrigger #475)
• DataTable: custom label and initial column visibility in DataTableColumnToggle (feat(data_table): support custom label and initial column visibility in DataTableColumnToggle #466)

Bug fixes

• Popover: sets data-state/data-side, clears closeTimeout on disconnect, closes on Escape ([Bug Fix] Popover: set data-state/data-side, clear closeTimeout on disconnect, close on Escape #495)
• Accordion: releases the panel height to auto after opening, so content that grows later is no longer clipped ([Bug Fix] Accordion clips content that grows after opening #500); docs controller synced with gem ([Bug Fix] Accordion: sync docs Stimulus controller with gem #490)
• Toast: toaster state moved to initialize() so a server-rendered toast inside Toaster no longer throws before connect() (fix(toast): initialize toaster state in initialize() so pre-existing targets don't throw #499)
• NativeSelect: viewBox capitalization on the chevron icon (fix(native_select): correct viewBox casing so the default chevron renders #467)

Infrastructure / docs site

• Docs Stimulus controllers are symlinks into gem/lib/ruby_ui/<component>/ instead of hand-maintained copies ([Improvement] Docs: symlink Stimulus controllers to gem source instead of copying #493)
• New RubyUI logo, wordmark and favicon set (Update favicon and icon set to new RubyUI logo #463, Update favicon and icon set to new RubyUI brand (red) #464, Update wordmark logo to new RubyUI brand #468, Fix favicon: apply the new red RubyUI mark #476)
• MCP: canonical www host in install instructions ([Bug Fix] MCP: point install instructions at canonical www host #492), rubyui.com allowed through DNS-rebinding protection ([Bug Fix] MCP: allow rubyui.com host in DNS-rebinding protection #491)

Verification

• cd gem && bundle exec rake — 281 runs, 1251 assertions, 0 failures, 0 errors; standardrb clean across 402 files
• Both Gemfile.lock diffs confirmed to be the ruby_ui version line only
• mcp/data/registry.json rebuilt and reports "version": "1.6.0"

Remaining release steps

1. Publish ruby_ui-1.6.0.gem to RubyGems (account has MFA — needs an OTP)
2. Merge this PR
3. Tag v1.6.0 on the merge commit, push the tag, cut the GitHub release — the release body is what feeds the changelog page, which renders from the GitHub releases feed
