fix(skill): use portable trailing-XXXXXX mktemp form for plan tmpfiles

Browse Source 
Greptile's review flagged mktemp -t as non-portable between BSD and GNU.
The suggested replacement (mktemp "$TMPDIR/...XXXXXX.json") is correct
about dropping -t but still puts X's in the middle of the template name
(XXXXXX.json), which BSD mktemp does not substitute — only X's at the
end of the basename are replaced on BSD. Verified on macOS:

  mktemp "$TMPDIR/last30days-test.XXXXXX.json"
  → /var/folders/.../last30days-test.XXXXXX.json  (X's left literal)

The fully portable form uses trailing X's and drops the .json suffix
(engine reads by path, not extension):

  mktemp "$TMPDIR/last30days-test.XXXXXX"
  → /var/folders/.../last30days-test.DXAHzR     (X's substituted)

Verified on bash and zsh, BSD/macOS. GNU/Linux is already fine since
GNU substitutes X's wherever they appear in the basename.

Applied to both --competitors-plan (comparison-mode block) and --plan
(Step 1 block) tmpfile writes.
