Narrow log parser API by making extractDomain internal

[Copilot]

extractDomain in src/logs/log-parser.ts was still exported even though it is only used internally and by tests. This PR removes that dead public export and updates tests to validate domain extraction through public parser behavior instead of a private helper.

• API surface cleanup

  • Removed extractDomain from the module’s public exports.
  • Kept all internal call sites (parseLogLine, parseAuditJsonlLine) unchanged.

• Test refactor to public contract

  • Dropped direct extractDomain imports from log-parser.test.ts.
  • Replaced helper-level unit assertions with parseLogLine cases that cover:
    • CONNECT domain extraction (with/without port)
    • host-header extraction for non-CONNECT requests
    • URL fallback paths (with/without protocol)
    • invalid URL fallback behavior

// before
export function extractDomain(url: string, host: string, method: string): string

// after
function extractDomain(url: string, host: string, method: string): string

Pull request overview

This PR narrows the public API of the Squid firewall log parser by making extractDomain an internal helper, and updates tests to validate domain extraction through the public parsing functions instead of importing the helper directly.

Changes:

• Made extractDomain non-exported (module-internal) in src/logs/log-parser.ts.
• Refactored log-parser tests to assert domain extraction via parseLogLine outputs rather than extractDomain calls.
