feat: add missing modules to pgpm export flow

[pyramation]

Summary

Syncs the export flow with the current state of pgpm-modules/metaschema-modules. Several modules were added, renamed, or removed in the upstream pgpm-modules repo but the export config here was stale.

Changes:

File	Change
pgpm/export/src/export-utils.ts	Add pgpm-partman to DB_REQUIRED_EXTENSIONS
	Remove pgpm-uuid from DB_REQUIRED_EXTENSIONS (vestigial — no SQL uses uuids.* functions, metaschema.control doesn't require it)
	Rename levels_module → events_module in META_TABLE_ORDER + META_TABLE_CONFIG (with new fields: events/aggregates/types tables, partition config, achievement rewards)
	Remove table_template_module (superseded by blueprints)
	Add inference_log_module config (partitioned inference log + usage_daily rollup)
	Add rate_limit_meters_module config (state, overrides, window_limits, check function)
	Add comment noting blueprint_template/blueprint/blueprint_construction are intentionally excluded
pgpm/core/src/modules/modules.ts	Add 'pgpm-partman': '@pgpm/partman' to PGPM_MODULE_MAP

Review & Testing Checklist for Human

• Verify events_module fields match the actual metaschema_modules_public.events_module table DDL
• Verify inference_log_module and rate_limit_meters_module fields match their table DDLs
• Run pgpm export against a provisioned database to confirm the new modules are picked up correctly
• Confirm removing pgpm-uuid from required extensions doesn't break any existing export flows

Notes

• Blueprint tables (blueprint_template, blueprint, blueprint_construction) are intentionally NOT in the export flow — they are runtime-only tables, not exported metadata
• table_template_module was removed from pgpm-modules (superseded by blueprints) — removed from config with a comment explaining why
• pgpm-uuid was removed because: no SQL references uuids.* functions, metaschema.control doesn't list it in requires, no pgpm-module depends on it. The uuid_module uses metaschema.uuid_seed GUC instead.
• Build passes cleanly (pnpm build at workspace root)
