APEXlang Skills: Version Router

APEXlang skills are versioned by Oracle APEX release. Route to the version that matches the target application, then load only that version's skills. Do not mix skills or example applications from different versions.

Supported Versions

APEX version	Start with	Skills
26.1	`26.1/SKILL.md`	`apexlang-generation`, `apexlang-compile`, `apexlang-deploy`, `apexlang-inventory`, `apexlang-example-applications`
26.2	`26.2/SKILL.md`	`apexlang-compile`, `apexlang-deploy`, `apexlang-inventory`, `apexlang-example-applications`

Choosing a Version

APEX 26.1: go to 26.1/SKILL.md.
APEX 26.2: go to 26.2/SKILL.md.
Read the version from mmdVersion in the application's .apex/apexlang.json, or from the target APEX instance. Match on major.minor: 26.1.x is 26.1 and 26.2.x is 26.2.
If the version is unknown, use 26.1.
If the application targets a version not listed here, tell the user which versions are supported before proceeding.
