feat(cli): add --match-contract filter to inspect command

[saturn-dbeal]

Adds a --match-contract flag to the cannon inspect command that accepts a regex pattern to filter which contracts are shown in the output.

This is useful when working with large deployments where you only care about specific contracts.

Usage:

# Show only contracts matching "Proxy"
cannon inspect my-package:1.0.0 --match-contract "Proxy"

# Export only specific contracts as JSON
cannon inspect my-package:1.0.0 --out artifact-json --match-contract "^Core"

# Write only matching contract deployments
cannon inspect my-package:1.0.0 --write-deployments ./output --match-contract "Token"

The filter works across all output modes:

• overview: Only shows matching contracts in the contract list
• artifact-json: Only includes matching contracts in the JSON output
• deploy-json: Only includes matching contracts from the deployment state
• --write-deployments: Only writes files for matching contracts

The pattern is applied recursively through nested imports.
