q98: register import_resolve_check.py on all three sweep axes and re-render docs/TOOLS.md

c30f372 landed tools/import_resolve_check.py and nothing registered it: the sweep read NO_PROBE on both input axes plus PIN_UNPINNED, write_probe read NO_PROBE on the json axis and failed its own c7 roster cell, and tool_map's HEAD drift cell failed on a TOOLS.md that did not name the tool. Measured at 7ffd177: verify.py 8 legs 5 pass / 3 fault (path-claims, selftest-sweep, write-axis); after this commit 7 pass / 1 fault, the remaining leg being the two inbox rows that faulted before this tick. Sweep: '23 tools, 21 OK, 2 fatal' -> 'verdict: rc 0 -- clean'; read-refusal 27 ok + NO_PROBE -> 28/28; malformed 26 ok + NO_PROBE -> 27/27; pin 22 pinned + 1 drift -> 23 pinned, 23 agree. write_probe: selftest 14/15 (c7 tool-only=['import_resolve_check.py']) -> 15/15, live axis 27 probed / 27 ok. The three new rows were graded against mutants of the tool, not assumed: refusal at rc 1 -> RC_NOT_2, not-a-repo graded clean -> RC_WRONG, --json silently skipped -> RC_OTHER. The tool itself is unmodified and still reads rc 1 on this tree (8 faults in 7 test files, Q98's subject). No other lane's file edited.
