Fix dependencies rake task to vendor correct ESM files for importmap

[Copilot]

The dependencies:vendor rake task was copying the UMD bundle (floating-ui.dom.umd.min.js) to vendor/javascript/floating-ui--dom.js, which is neither referenced by the importmap nor the correct format for it. Meanwhile, the ESM files the importmap actually pins (@floating-ui--core.js and @floating-ui--dom.js) had no automated source.

Changes

• tasks/dependencies.rake: Replace UMD copy with two ESM copies:
  • @floating-ui/core/dist/floating-ui.core.browser.mjs → vendor/javascript/@floating-ui--core.js
  • @floating-ui/dom/dist/floating-ui.dom.browser.mjs → vendor/javascript/@floating-ui--dom.js
• vendor/javascript/floating-ui--dom.js: Delete the UMD file — it was unreferenced and a stale artifact of the old task.

# Before
FileUtils.cp(
  File.join(node_modules, '@floating-ui', 'dom', 'dist', 'floating-ui.dom.umd.min.js'),
  File.join(vendor, 'floating-ui--dom.js')
)

# After
FileUtils.cp(
  File.join(node_modules, '@floating-ui', 'core', 'dist', 'floating-ui.core.browser.mjs'),
  File.join(vendor, '@floating-ui--core.js')
)
FileUtils.cp(
  File.join(node_modules, '@floating-ui', 'dom', 'dist', 'floating-ui.dom.browser.mjs'),
  File.join(vendor, '@floating-ui--dom.js')
)

The rake task now serves as the authoritative source for regenerating both vendored floating-ui files.
