`detail` called fetch() directly rather than going through the CLI's own
request wrappers, so it had none of the three things apiFetch/apiPost
guarantee: no 429/5xx retry loop, a hand-inlined User-Agent that would
drift from the exported USER_AGENT, and a timeout no wrapper test covered.
A rate-limited detail page wrote API_ERROR and exited after ONE attempt;
jobnet, jobbank, jobindex, linkedin, and freehire all retry up to six
times on the same response. /scrape calls detail once per shortlisted
posting, so a burst that tripped jobdanmark's limiter dropped those
postings (no description, no deadline) while any other portal rode it out.
Demonstrated by driving the real command handler with a stubbed 429 and
instant timers: 1 fetch attempt and exit 1 before, 7 after (initial try
plus six retries, the contract's schedule).
Add htmlFetch to helpers.ts with the same backoff, timeout, and shared
User-Agent as the JSON wrappers - 404 returns null so detail keeps its
NOT_FOUND contract - and route detail through it. The retry-backoff,
user-agent, and request-timeout suites now cover all three wrappers, and
the new detail-backoff.test.ts exercises the handler path itself; its two
retry cases fail against the bare fetch().
* fix(cli): send User-Agent on jobnet and jobdanmark API requests
apiFetch/apiPost hit the portals' APIs without a User-Agent header, while every other Danish-portal CLI sends one on purpose (jobbank exports USER_AGENT and its tests assert it; jobindex sets it on htmlFetch). Requests without one are rejected by the portals' bot filters.
* fix(cli): satisfy strict typecheck in user-agent regression test
* refactor(cli): reframe user-agent tests as honest self-identification
* docs(changelog): entry for #283 user-agent self-identification
