Add the integration train: Waves 0–5 dependency-ordered manifest + verifier [supersedes #11]

[estebanzimanyi]

Summary

Supersedes #11. The original PR's branch lives on MobilityDB/MEOS-API:feat/integration-train (predates the fork-branch-only policy). This PR rebuilds it from the fork with the additive Wave 4 + Wave 5 manifest entries:

Update	Where
Wave 4 — Downstream bindings (MobilityDuck / MobilitySpark / MobilityAPI / JMEOS / GoMEOS / MEOS.NET)	meta/integration-train.json#/waves[4]
Wave 5 — Service-agent + data-lake + stream layers (anchor-defined)	meta/integration-train.json#/waves[5]
Ecosystem repo enumeration broadened in doc preamble	docs/integration-train.md
Stripped "owner: live X session" framing per the standing-down memory	meta/integration-train.json
Current-status line updated for 2026-05-21	both files

Wave 4 — what's in it

Each binding regenerates against the Wave-0 MEOS-1.4 C surface via the meos-idl.json catalog. Each is bump-independent within its repo; the cross-binding gate is byte-identical regeneration (proves single SoT).

Wave 5 — what's in it

• Service-agent layer — MEOS-API feat: derive service-projection metadata for the catalog #4/feat: generate an OpenAPI 3.1 contract from the enriched catalog #5/feat: generate an MCP tool manifest from the enriched catalog #6/feat: contract-driven runtime HTTP server with a pluggable MEOS engine #7/ci(openapi): add openapi-validate workflow (PR #5 natural follow-up) #12/feat: generate an OGC API – Moving Features OpenAPI projection (PR #5 follow-up) #13; consumed by MobilityAPI feat: canonical portable bare-name mapping as the codegen source of truth #8.
• Data-lake layer — first consumer MobilityDuck #146/#147/#158; second consumer PyMEOS #84. Polaris readiness doc (per [[apache-polaris-readiness]]) ships when substrate lands.
• Stream layer — PLANNED_BAND: MobilityFlink docs: add Ecosystem section listing MobilityDB org projects #3 + MobilityKafka Prepend a stdbool stub when invoking libclang on MEOS headers #1 + MobilityNebula feat: generate an OGC API – Moving Features OpenAPI projection (PR #5 follow-up) #13/Add the integration train: Waves 0–5 dependency-ordered manifest + verifier [supersedes #11] #14.

Branch base

This PR is on feat/integration-train (fork) and uses the same base as #11: feat/object-model (MEOS-API PR #10). Stack relationship unchanged.

Action requested

• Close Add the integration train: provable ecosystem-wide 100% parity #11 in favour of this PR.
• This PR lives in the MEOS-API fork at estebanzimanyi:feat/integration-train, matching the standard fork-only pattern.
