Subject: [PATCH] feat: Add pg_partman 5.5.0 as a SQL-only extension (NO_BGW)

pg_partman's core is pure SQL/PLpgSQL; the only C component is its
background worker, which schedules run_maintenance() and cannot exist
in single-process WASM. Upstream officially supports building without
it via NO_BGW=1, so the extension is packaged SQL-only and maintenance
is invoked by the embedding application instead.

The submodule is pinned at the v5.5.0 release tag. It is intentionally
kept out of SUBDIRS so the recursive 'all' build never attempts to
compile the background worker with emscripten; only the dist rule
touches it.
