Convert commands and context to skills, add skills symlinks to Rexfile

Move purge-file-from-git, compose-blog-post, increment-version-and-push
from commands to skills format, and convert go-best-practices from context
to a skill. Update Rexfile home_prompts task to symlink both commands and
skills directories for cursor, claude, agents, and opencode.

+
+# Increment version and push
+
+Increment the version of the project, tag it in git, commit, and push.
+
+## When to Use
+
+- Use this skill when the user wants to bump the version and release/push a project.
+
+## Instructions
+
+- For Go-based projects, look for the `internal/version.go` file.
+- We use semantic versioning: `x.y.z`.
+  - For bug fixes, increment only `z` (the patch version).
+  - For new features, increment `y` (the minor version) and reset `z` to 0.
+  - Never increment `x` (the major version) unless explicitly specified.
+- Commit the version change, create a git tag matching the new version, and push both the commit and the tag.
