- Explicit MIME map for common image/doc types instead of relying on system mimetypes db (fixes empty file.type on sites like Medium) - --mime CLI flag to override auto-detected MIME type - Send Escape keypress after upload to dismiss lingering OS file picker - Log detected MIME type at info level
Break long lines to fit 100-char limit, fix undefined name SessionInfo via TYPE_CHECKING guard, remove unused test variables. No functional changes.

Summary
mimetypes.guess_typemime_typeparameter onBrowser.upload()for explicit override--mimeCLI flag onceki uploadcommandInput.dispatchKeyEvent) after upload completesContext
Medium and other sites with MIME validation rejected uploads because
File.typewas empty when systemmimetypesdb lacked entries. Explicit map ensures common image/doc types always resolve correctly regardless of host OS.The OS file dialog could linger after upload, blocking subsequent interactions. Auto-dismiss via Escape fixes this.
