NONEVM-3462: devenv smoke testing

[jadepark-dev]

Testing devenv go mod tidy failure, suspecting outdated chainlink-ton deps in core

• failed go mod tidy: https://github.com/smartcontractkit/chainlink-ccip/actions/runs/21151593265/job/60828581047#step:6:600
  • bump ton in core: chore(deps): bump chainlink-ton chainlink#20842
• failed with 24816 https://github.com/smartcontractkit/chainlink-ccip/actions/runs/21152382997/job/60830818838#step:14:44
  • added missing link price dc62ef9 (#535)

Pull request overview

This PR enables TON smoke testing in the development environment by updating dependencies and fixing price configuration issues. The changes address failures in go mod tidy and missing LINK token price configuration that were preventing successful smoke test execution.

Changes:

• Updated chainlink core version reference to resolve dependency conflicts
• Fixed LINK token price configuration in the TON fee quoter
• Re-enabled smoke test workflow with improved logging

The multiplication operation mutates linkTokenPrice and then multiplies it by itself (since Mul's receiver is also the first operand), resulting in linkTokenPrice² * 1e10 instead of the intended linkTokenPrice * 1e10. Use a new variable or swap the operands: linkTokenPrice = big.NewInt(0).Mul(linkTokenPrice, big.NewInt(1e10))

Suggested change

	linkTokenPrice = linkTokenPrice.Mul(linkTokenPrice, big.NewInt(1e10)) // Scale to 1e28
	linkTokenPrice = big.NewInt(0).Mul(linkTokenPrice, big.NewInt(1e10)) // Scale to 1e28

The comment states 'LINK has 9 decimals on TON' but the scaling factor of 1e10 applied to a base of 1e18 suggests different precision handling. The relationship between the 9 decimals, the 1e18 base amount, and the 1e10 scaling factor should be clarified to explain why 1e28 is the target precision.

Suggested change

	const TONtoUSD = 2 // Example value
	const TONtoNanoTON = 1e9 // Smallest denomination
	const TokenPriceBaseAmount = 1e18 // Defined for `TokenPrices`
	var USDDecimals = big.NewInt(1e18) // Defined for `TokenPrices`
	// Calculate TON token price
	var TONBaseAmountTokenPrice = big.NewInt(int64(TONtoUSD * (TokenPriceBaseAmount / TONtoNanoTON)))
	tonTokenPrice := big.NewInt(0).Mul(TONBaseAmountTokenPrice, USDDecimals)
	// Calculate LINK token price (20 USD with 1e18 precision)
	// LINK has 9 decimals on TON, similar to Solana
	linkTokenPrice := big.NewInt(0).Mul(big.NewInt(20), big.NewInt(1e18))
	linkTokenPrice = linkTokenPrice.Mul(linkTokenPrice, big.NewInt(1e10)) // Scale to 1e28
	const TONtoUSD = 2 // Example value
	const TONtoNanoTON = 1e9 // Smallest denomination
	const TokenPriceBaseAmount = 1e18 // Base amount used for TokenPrices, in 1e18 USD precision
	const TokenPricePrecisionScale = 1e10 // Additional scale so that TokenPrices use 1e28 precision (1e18 * 1e10)
	var USDDecimals = big.NewInt(1e18) // USD values are expressed with 1e18 precision
	// Calculate TON token price
	var TONBaseAmountTokenPrice = big.NewInt(int64(TONtoUSD * (TokenPriceBaseAmount / TONtoNanoTON)))
	tonTokenPrice := big.NewInt(0).Mul(TONBaseAmountTokenPrice, USDDecimals)
	// Calculate LINK token price:
	// - Start from 20 USD represented with 1e18 USD precision.
	// - LINK has 9 decimals on TON, but TokenPrices are normalized to 1e28 precision
	// (1e18 USD precision * TokenPricePrecisionScale = 1e28), independent of token decimals.
	linkTokenPrice := big.NewInt(0).Mul(big.NewInt(20), big.NewInt(1e18))
	linkTokenPrice = linkTokenPrice.Mul(linkTokenPrice, big.NewInt(TokenPricePrecisionScale)) // Scale USD value to 1e28 TokenPrices precision

The comment 'Example value' suggests this is a placeholder rather than a real price. If this is production code, it should use actual price feed data or be clearly documented as a test/development constant.

Suggested change

	const TONtoUSD = 2 // Example value
	const TONtoUSD = 2 // Test/development placeholder value; do NOT use in production (use a real price feed or config instead)
