fix(ci): push the verification status refresh to TechAPI develop

[Seungpyo1007]

Problem

verify-status checks out TechAPI's default branch — develop since the git-flow switch — commits the refreshed status.json there, and then pushes HEAD:main. main has not moved since, so the push is rejected and every run fails after doing all of its work:

[develop b16923c] chore(verify): refresh verification status aggregate
 1 file changed, 74 insertions(+), 47 deletions(-)
! [rejected]   HEAD -> main (fetch first)
error: failed to push some refs to 'https://github.com/GetTechAPI/TechAPI'

data/_verify/status.json on develop is consequently stale since 2026-07-31 — it still reports 14,777 verified when the real figure is 20,777, and it is what the homepage renders.

Change

• push HEAD:develop
• pin ref: develop on the TechAPI checkout so the branch worked on cannot drift from the push target again
• git pull --rebase origin develop first, since several bots write to develop and a status refresh is not worth failing over a race

bump-techapi.yml also pushes HEAD:main, and that one is correct — it targets TechEngine's own main, which has no develop.

This is the last of the git-flow leftovers; the same class of fix as #54 (weekly-ingest) and #50 (promotion PRs).
