Documentation Updates - 2026-04-07

This PR updates the documentation based on user-facing features merged as part of the v0.8.11 release.

Features Documented

• GITHUB_HOST support in apm marketplace add for GitHub Enterprise users (from fix: respect GITHUB_HOST in marketplace add command #589)
• compilation.exclude now filters primitive discovery, not just compiled output (from Fix: compilation.exclude does not filter primitive discovery #477)
• apm compile warning when instruction files are missing applyTo frontmatter (from fix: warn when instruction is missing required fields during apm compile #449)
• Native skill name collision warning when two packages deploy a skill with the same name (from [fix] warn when two packages deploy a native skill with the same name #545)

Changes Made

• Updated docs/src/content/docs/guides/marketplaces.md — added a GitHub Enterprise Server note in the "Register a marketplace" section explaining that apm marketplace add respects GITHUB_HOST for bare owner/repo references, matching behavior with apm install
• Updated docs/src/content/docs/guides/compilation.md — clarified that compilation.exclude filters primitive discovery before scanning (not just final output), and added a callout warning about the missing applyTo frontmatter behavior
• Updated docs/src/content/docs/guides/skills.md — added a "Native Skill Name Collision" troubleshooting entry explaining the warning emitted when two installed packages deploy a native skill with the same name

Notes

The following v0.8.11 changes were intentionally not documented as they are internal implementation improvements with no user-visible API or behavior change:

• Scope resolution refactoring (refactor: unify integration dispatch, result types, and hook dedup #562) — internal dispatch architecture
• Subprocess UTF-8 encoding fix (fix: subprocess encoding failures on Windows non-UTF-8 consoles (CP950/CP936) #591) — transparent Windows improvement
• PowerShell 5.1 compatibility fix (fix: use nested Join-Path for PowerShell 5.1 compatibility #593) — transparent Windows improvement
• Detect remote default branch ([fix] detect remote default branch instead of hardcoding main (#573) #574) — internal improvement, no user action required
• Symlink rejection in primitive discovery (fix: enforce symlink containment in file discovery and resolution #596) — security hardening, no new user-facing options
