chore: remove repo-level PR template

[jamesnrokt]

Why

This repo carries its own .github/PULL_REQUEST_TEMPLATE.md, which GitHub prefers over the org-wide default template published in mParticle/.github. That means new PRs here silently skip the shared template every other @mParticle/sdk-team-owned repo is meant to use. Once this lands, opening a new PR here shows the same org-wide template contributors see everywhere else.

Programme

Standalone change, no programme.

What changes

Deletes .github/PULL_REQUEST_TEMPLATE.md. Nothing else changes. New PRs opened against this repo now fall back to the org-wide default at mParticle/.github (.github/PULL_REQUEST_TEMPLATE.MD).

Linked work

None.

Rollout

Nothing changes in production; if this is wrong, revert the pull request.

Risks

• The deleted template linked two repo-specific CI checks (PR title format, PR branch prefix format) that contributors won't see spelled out in the PR description anymore. Those checks are still enforced by CI regardless of the template text, so nothing merges silently wrong — the risk is a contributor's first PR failing that check with no local hint why, not a functional break.

Risk class: low.

Who

Written by: automated coding agent (Claude Code), on behalf of the requesting engineer — standalone repo-hygiene request, no linked ticket.
Code reviewed before opening: an independent review agent, before the commit was made.
Design reviewed before opening: no one.
Decision this implements: a standalone request (2026-09-16) from the repo owner to remove repo-level PR template overrides across every mParticle-org repo owned by * @mParticle/sdk-team, so each one falls back to the org-wide default. No ticket.
Checked: confirmed the PR-title and PR-branch-prefix checks referenced by the deleted template are still enforced via .github/workflows/reusable-workflows.yml regardless of the template text; confirmed no other file under .github/workflows/ references PULL_REQUEST_TEMPLATE; confirmed mParticle/.github publishes an org-wide default template.
Not checked: nothing else touched, nothing else to check.

Size

Hand-written: 0 lines added, 13 lines removed, 1 file deleted.
Generated: none.

PR Summary
