chore(deps-dev): bump the npm-security-and-maintenance group across 1 directory with 4 updates

[dependabot]

Bumps the npm-security-and-maintenance group with 4 updates in the / directory: hardhat, prettier, prettier-plugin-solidity and tsx.

Updates hardhat from 3.9.1 to 3.12.0

Release notes

Sourced from hardhat's releases.

Hardhat v3.12.0

This release includes two new features: negative test filtering with the --grep-exclude flag for both Solidity tests and Mocha test suite, and experimental Amsterdam "EIP-7843: SLOTNUM" support, see our Amsterdam support guide.

Changes

• #8442 4904c72 Thanks @​ChristopherDedominici! - Support test name filter negation (--grep-exclude) for Solidity and Mocha tests.

• #8472 2a66c2e Added experimental EIP-7843 support to the Amsterdam hardfork: blocks now include the slotNumber header field, and the SLOTNUM (0x4b) opcode returns it. EDR has no consensus layer, so the value is simulated: it increments by one per mined block, starting at 0 on a new chain, or from the forked block's slot number when forking.

• #8464 b2b69f7 Thanks @​nishant-uxs! - Prefer environment variables over configurationVariables hooks when resolving config vars.

• #8474 49cc2f0 Thanks @​Wodann! - Report chain type to Google Analytics

• #8458 0c60e08 Thanks @​schaable! - Fixed project initialization so that compilation and build output directories are never copied from a template into a new project.

• #8472 2a66c2e Thanks @​kanej! - Fixed empty stack traces on Solidity test failures when running with -vvv or above.

• #8472 2a66c2e Thanks @​kanej! - Fixed missing stack traces when an invariant already fails on its initial check, when running with -vvv or above.

• #8470 341807c Thanks @​kanej! - Update the chokidar runtime dependency to its latest major version.

• #8470 4a71543 Thanks @​kanej! - Update the p-map dependency.

• #8461 841423a Thanks @​kanej! - Reduce installation warnings with updated dependencies.

Hardhat v3.11.1

This release removes the Hardhat 2 option from project initialization and fixes how Solidity files are classified when the same directory is configured for both sources and tests.

Changes

• #8451 5c9d4a4 Thanks @​kanej! - Remove Hardhat 2 option from init process

• #8452 724b7cd Thanks @​kanej! - Fixed Solidity source classification so that a directory listed in both paths.sources.solidity and paths.tests.solidity is treated as a source.

• Updated dependencies:

  • @​nomicfoundation/hardhat-utils@​4.1.6

Hardhat v3.11.0

This release adds two further EIPs to Hardhat's experimental Amsterdam support: EIP-7778: block gas accounting without refunds and EIP-7928: Block-Level Access Lists. See our Amsterdam support reference for full details of how these work within Hardhat.
