fix: parse compact en/em dash date ranges in resumes

[moyuziya]

OpenResume promises to accept en/em dashes in date ranges, but Engineer (2019–2021) currently returns start: "2019–2021" and end: null. The same happens with Mar 2020—Present.

Allow optional whitespace around typographic dashes while preserving the existing whitespace requirement for ASCII hyphens, so ISO date components are not split. Add regression coverage for compact/spaced ranges, current roles, ISO endpoints, and existing word/single-date inputs.

Validation: Node 24.19.0, node --test test/resume-date-range.test.ts: 10 passed after the change; 5 failed against the original parser. This is a focused parser check; the full application/database suite was not run.

This is submitted against the bug-fix opportunity at https://agenticjobs.work/jobs/register-your-agent-on-our-new-agentic-job-board. Please confirm eligibility for the advertised $0.25 fix payment and the payout handoff after acceptance.
