build(deps-dev): bump hardhat from 2.28.6 to 3.9.1

[dependabot]

Bumps hardhat from 2.28.6 to 3.9.1.

Release notes

Sourced from hardhat's releases.

Hardhat v3.9.1

This release improves Solidity Tests with configurable transaction gas caps and safer gas snapshot checks, while also making Hardhat faster to start and easier to migrate to from Hardhat 2.

Changes

• #8234 81871fd Thanks @​tenderdeve! - Explain the unsupported cheatcode eip712HashType(string,string) and point to the documentation for the alternative instead.

• #8400 2f48724 Thanks @​kanej! - Support setting the transaction gas cap in Solidity Tests

• #8367 82d00fc Thanks @​alcuadrado! - Lazy load dependencies to optimize bootstrap time

• #8391 f3c5727 Thanks @​schaable! - Make hardhat test solidity --snapshot-check read-only. It no longer rewrites or deletes .gas-snapshot or snapshots/*.json files, and instead reports differences. The command now fails when a stored gas value differs from the current one, or when no baseline exists, with a hint to run --snapshot.

• #8332 e542a48 Thanks @​gultekinmakif! - Fixed a crash that could occur when a network returned an unexpected response while resolving the default sender account

• #8385 946e379 Thanks @​BROCCOLO1D! - When a Hardhat 2 plugin calls an API that no longer exists in Hardhat 3, the error now names the specific API that was used and explains how to migrate it to Hardhat 3.

• Updated dependencies:

  • @​nomicfoundation/hardhat-errors@​3.0.16
  • @​nomicfoundation/hardhat-utils@​4.1.4

Hardhat v3.9.0

This release adds support for excluding files from test coverage instrumentation and reporting (i.e. npx hardhat test --coverage).

Changes

• #8380 0fd498d Thanks @​kanej! - Added support for coverage.skipFiles, a list of globs of Solidity files to exclude from coverage instrumentation and reporting during a --coverage run.

• #8383 1660f1e Thanks @​schaable! - Fixed an intermittent "Provider for provided chain type does not exist" error that could occur when multiple network connections were created concurrently.

• #8371 287620e Thanks @​gultekinmakif! - Account overrides that share an address with the network's built-in genesis accounts are now correctly merged into a single genesis entry.

• #8375 931a5f0 Thanks @​schaable! - Suppressed the solc initcode size warning for Solidity test contracts and when running under --coverage.

• #8372 5f6aff2 Thanks @​gultekinmakif! - Improved validation for initialDate network configuration. Invalid Date objects and unparseable date strings are now rejected during config loading rather than causing a runtime error later.

Hardhat v3.8.0

This release includes two improvements: a warning is now printed if a plugin is imported in hardhat.config.ts but not included in the plugins array and node:test now more cleanly displays Solidity errors.

Changes

• #8339 f21390f Thanks @​alcuadrado! - Added definePlugin, a new helper exported from hardhat/plugins. Plugin authors should wrap their plugin literal with it so the default export of their index module becomes:
