feat: remove @iexec/interface & @iexec/solidity dep

[Le-Caignec]

After removing @iexec/solidity and @iexec/interface dependencies, all tests started failing with:

Error: missing field `ast` at line 1 column 7136
  at Function.create (node_modules/hardhat/src/internal/hardhat-network/provider/provider.ts:182:37)

Hardhat failed to initialize its network provider because Solidity 0.4.11 produces a legacyAST field in the build info instead of the modern ast field.
Since Hardhat only supports the standard ast format, build-info files from Solidity 0.4.11 caused compatibility issues during deployment or testing.

Solutions Applied

1. Updated the Solidity compiler version

• Replaced Solidity 0.4.11 with Solidity 0.4.26, which still belongs to the 0.4.x series but generates a standard ast field that Hardhat can process correctly.

2. Removed the custom outputSelection

• The manual outputSelection was overriding Hardhat’s default configuration and excluded ast.
• By removing it, Hardhat now uses its default output selection, which automatically includes the correct ast output for all source files.

Change from 0.4.11 to 0.4.26: produces a standard ‘ast’ output

[gfournieriExec]

why remove this ?

[Le-Caignec]

This prevents Hardhat from producing an ast in the build files.
