fix(claude_code/conftest): record fail on setup error or partial crash

Two related gaps in pytest_runtest_makereport let real failures show up as
green (or absent) cells in the published compatibility matrix:

1. Setup-phase failures (broken fixtures / imports) only produce a report
   with when="setup"; the call phase never runs. The hook filtered on
   when=="call" and returned, leaving no row for the cell. The matrix
   builder then aggregated the empty cell to "not_tested" instead of
   "fail".

2. A test that called compat_result.add({"status": "pass"}) for some
   models and then raised before completing the rest produced a partial
   list of pass entries. The "if not collected" guard was bypassed
   because the list was non-empty, so no fail row was added. The cell
   aggregator's all-pass check then returned pass for a cell that was
   never fully exercised.

Now the hook also handles when=="setup" on failure, and always appends a
fail row when report.failed — preserving any partial pass entries from
add() for diagnostics while ensuring the cell aggregator surfaces the
crash.
