v0.2.1

A bug-fix release. Both fixes are about the tracker letting something through
that it should have stopped, and neither showed up as an error.

A second application to the same company could be rejected silently

Greenhouse lets an employer auto-reject a candidate's further applications to a
department within a window, or after a rejection. The rejected application is
marked "blocked by auto reject rule", and the candidate is told only if the
employer has switched the email on. Seekter treated a second role at the same
company as a fresh posting, and on a good day it could send several. Measured
2 Oct: two roles at one company and a second role at another went out the same
afternoon. If the employer uses that rule, the second one may never have been
read, and to a recruiter it looks like the mass applying they filter out.

check now holds the company: it exits 2 with HOLD when there is already an
application, a pending hand-off or a rejection there within the window, or an
interview or offer at any date. The run skips a held posting, says which earlier
role and date held it, and lists it under its own heading in the report so you
can overrule it. When one run finds two roles at the same company, only the
better fit goes out. A link you bring yourself counts as your decision and is
applied, with a note. The window is same_company_days in profile/search.json,
30 days by default.

check passed a bare LinkedIn id as new

check-many has always read a bare number as a LinkedIn job id. check did not:
it keyed the number as it was, matched nothing, and printed NEW for a job
already in the tracker. Since 0.2.0 tells the run to dedup alert-mail postings
on their LinkedIn id, that check could have let a duplicate through. Both
commands now read the number the same way.

Also

• One local-language search term in the Indeed notes was spelled in plain
  ASCII, so the 0.2.0 language sweep missed it.

Upgrading

Nothing to migrate. Without same_company_days in profile/search.json, the
window is 30 days; add the key to change it. profile/, applications/ and
runs/ are git-ignored and untouched.
