Adds tests/pgserver/run.sh, the integration gate for the wire
layer. Builds a minimal bootstrap PRG that opens nothing and just
calls PG_SERVER_START on an ephemeral port, then drives psql with
a Simple Query to confirm the end-to-end pipeline (TCP accept →
startup handshake → Query → five_SQL → RowDescription + DataRow
→ ReadyForQuery) still works after every change.
Phase 3 verified scope (driven via a separate pgx harness during
development):
* CREATE TABLE / INSERT / UPDATE / DELETE over Simple Query
* BEGIN / COMMIT / ROLLBACK from the wire
* Two-connection cross-visibility on a shared DBF
* Per-session ROLLBACK leaves the *other* connection's data
intact — the Phase 1 STATIC → TSqlSession refactor is what
makes this hold; pre-refactor, both connections would have
shared one s_aTxnLog and A's ROLLBACK would have collapsed
B's COMMIT.
Known limitation captured in the script header (deferred to
Phase 7 follow-up):
* ≥3 concurrent connections doing in-flight INSERT/SELECT in
their own transactions occasionally race at the hbrdd
workarea layer — surfaces as one worker's just-inserted row
missing from its own SELECT. 2-way concurrent + N-way serial
are both reliable. Root cause is multi-thread workarea
arbitration during dbUseArea/dbAppend, which the pre-1.0
audit flagged as Top-Risk #2 ("WorkArea collision under
multi-session"). Tracking for a dedicated fix.
