Add SafeAgent to Security & Trust

[Bemosha]

Adds SafeAgent, an open-source (MIT) Chrome extension that detects four attacks aimed at crypto users:

• Clipboard address substitution — compares the copied wallet address against the buffer for 60s
• Approval signatures — inspects approve / setApprovalForAll / permit before the request reaches the wallet
• Seed-phrase input forms — DOM scan for 12/24-word layouts
• Phishing and typosquatted domains

Detection is local, with no accounts or telemetry.

One thing to flag: the intro line under Security & Trust describes tools that evaluate the safety of other extensions, which is narrower than the category name. SafeAgent protects the user rather than rating extensions, so it may not be what you intended for that section. Happy to move it, or to add a separate category if you would prefer one — your call, and no hard feelings if it does not fit the list.
