[YoshiyukiSakura]

Refs #2

Change:

• Auto-detect obvious search input types before database lookup.
• Add EVM contract lookup support and address helper coverage for ambiguous EVM addresses.

Objective Evidence:

• go test ./util/address passed.
• go test -c ./internal/server/http -o /tmp/subscan-http.test passed.
• go test -c ./plugins/evm/dao -o /tmp/subscan-evm-dao.test passed.
• git diff --check passed.

Visual Evidence:

• n.a. Backend/API-only search classification change; no rendered UI changed.

Reviewer:

• Manual operator recovery after CrossAgent GitHub App push failed with 403.

Risks / Not Covered:

• Full service integration still depends on local configs and database bootstrap.
