fix(ci): resolve leftover merge-conflict markers in 3 files

.github/workflows/instant-sync.yml, .github/workflows/semgrep.yml, and
.github/FUNDING.yml all had unresolved <<<<<<< HEAD / ======= / >>>>>>>
markers committed straight to main from a prior "sync from parent repo
automation" merge. In all three cases both sides of the conflict were
identical (a duplicated SPDX header line) — collapsed to one copy.

A file with literal conflict markers isn't valid YAML, so CI (including
CodeQL's "actions" language analysis) has been failing on every PR
against this repo regardless of the PR's own diff, since the problem
lives in the base branch, not any individual PR.
