mxcli syntax: see-also link to schema show

[ako]

Parent: #540 (v0.11.0 workflow integration)

Goal

Each `mxcli syntax ` entry should link to the registry-derived raw schema reference, once that reference exists.

Background

#540 listed this as work:

Existing topic content stays. Each topic gains a "see also: `schema show `" link to the registry-derived raw reference (registry inspection lands in v0.11+).

It wasn't delivered with #540 because the registry-inspection commands (`mxcli schema list/show/diff`) are deferred to v0.11+ per #540's own "Out of scope" section. The link target literally doesn't exist yet.

Work

• After the schema-inspection commands land (likely Unified Schema Registry: replace TS reflection + supplements + embedded widget templates #529 Phase 4 codegen), add a `SeeAlso` field to `cmd/mxcli/syntax/SyntaxFeature` entries
• Render the see-also section in `mxcli syntax ` output and in REPL `help` output
• Populate the see-also field for every topic that has a corresponding `schema show` target

Acceptance criteria

• Every relevant `mxcli syntax ` shows a see-also link
• The link resolves: `mxcli schema show ` works

Issue Triage

Summary:
The issue requests adding a “see also” link from each mxcli syntax <topic> entry to the corresponding mxcli schema show <type> command once the schema‑inspection commands are available.

Checklist for feature request

Required info	Present?	Notes
Use case – why the feature is needed / what problem it solves	✅	Described in the Goal and Background sections (link syntax topics to schema reference).
Proposed syntax or behavior (if applicable)	✅	Proposes adding a SeeAlso field to SyntaxFeature and rendering it in mxcli syntax output and REPL help.
Mendix version relevance (if version‑specific)	⚠️	Not explicitly mentioned; the feature is tied to mxcli’s schema‑inspection work rather than a specific Mendix version, so version relevance is not required.

Feedback:
The issue provides a clear use case and the proposed implementation. Since the feature isn’t tied to a particular Mendix version, the missing version‑specific detail isn’t needed. The request looks complete—thanks for the thorough description!
