v0.5.4

New features

• Added direct double-click access to Download Properties for unfinished downloads.
• Added a make verify command for local build and Firefox extension manifest checks.

Changes

• Updated Firefox integration to probe the same local fallback ports used by the app.
• Updated global speed limiting so changes apply to active downloads through aria2 RPC.
• Declared SwiftPM resources and added development fallbacks for app icons and Firefox extension copying.
• Narrowed saved site-login matching so plain host patterns match exact hosts unless a wildcard is used.

Fixes

• Fixed browser handoff failures when the default local extension port is unavailable.
• Fixed dropped Referer headers from browser extension requests.
• Fixed scheduler configurations that could be enabled without any runnable queue target.
• Fixed unsafe file names from URLs, metadata responses, and manual property edits.
• Fixed a possible duplicate-open glitch when double-clicking unfinished downloads.
