Greptile Summary

This is a documentation-only PR that adds a "Multi-file configuration" section to the CLI installation page and threads cross-links to it from all affected resource pages (functions, sites, buckets, teams, topics, tables) and product deployment pages.

• Installation page gains the authoritative multi-file config section covering the includes field, path-resolution semantics, and security constraints on include paths (no parent-directory traversal, no URLs, etc.).
• Resource pages (buckets, functions, sites, tables, teams, topics) and commands page each get a short paragraph and arrow_link pointing readers to the new section.
• Changelog entry announces the feature for CLI 20.0.0 but lists a slightly shorter set of supported keys than the installation page (omits databases and collections).

Confidence Score: 5/5

Documentation-only change with no code execution paths affected; safe to merge.

All changes are Markdoc documentation files. The cross-links are internally consistent, the new installation section is well-structured with clear path-security constraints, and no existing content is removed. The only discrepancy is a minor omission of two supported keys in the changelog prose compared to the canonical list on the installation page.

src/routes/changelog/(entries)/2026-05-06.markdoc — the supported-key list is incomplete relative to the installation page.
