gsxdsm de1638e262 FN-8090: use mmap shared memory for embedded PostgreSQL
Enable constrained-host embedded PostgreSQL startup without SysV shared-memory exhaustion.

- Default embedded lifecycle flags to mmap-backed shared memory while preserving caller overrides
- Cover normal and elevated Windows launch paths with deterministic flag propagation tests
- Document the 64MB /dev/shm support floor and add a patch changeset

Changeset Format Guide

Each changeset file in this directory describes one user-facing change for release notes.

Required body format

---
"@runfusion/fusion": minor
---

summary: Add a Command Center productivity control for LOC backfills.
category: feature
dev: Uses the new `fn_backfill_loc` tool; settings key `commandCenter.locBackfill`.

Fields

Field Required Description
summary Yes One line, user-facing, max 120 chars. Describe what changed for the operator.
category Yes One of: feature, fix, breaking, security, performance, internal.
dev No Developer or migration detail. Preserved in per-package CHANGELOGs but excluded from distilled release notes.

Audience

The summary is the only content that appears in end-user release notes by default. Write for Fusion operators — describe behavior, fixes, and what changed. Avoid internal class names, file paths, and implementation detail.

Bump types

  • patch — bug fixes, internal changes
  • minor — new features, CLI additions, tools
  • major — breaking changes

Validation

Run pnpm check:changesets to validate. The linter runs in the PR-check gate and test:gate. Legacy freeform changesets pass with a warning during the transition period.
