[Spike] Action Menu on text highlight

[Pashaminkovsky]

Motivation

We're looking to improve AI writing, translation, and summarization mods. The goal of this spike is to gauge the complexity of implementing an "Action Menu" similar to what Grammarly and moly.ai have implemented (see screenshot below).

The ideal flow would be:

1. User highlights text
2. Action Menu opens near text
3. User can choose an action, type a prompt, etc.
4. Action Menu presents results to the user, who can can choose to insert text at cursor, or choose other actions.

Note: Compatability with Google Workspace is out of scope, the screenshot is meant to highlight the Action Menu.

The Action Menu would appear as an option in the "New Mod" selection in the page editor, and would be mutually exclusive with the Text Selection Menu (emojis that appear on highlight).

The exact naming of "Action Menu" is tbd -- we're open to suggestions.

Acceptance Criteria

• T shirt sizing on implementation, and high-level steps / constraints / unknowns are mapped out
