[FEATURE] Git remote/org condition for rules frontmatter

Problem Statement

Rules files support paths frontmatter conditions, but there's no way to scope rules based on which org owns the repo. When working across multiple orgs on one machine, user-level rules (~/.claude/rules/) either apply to everything or nothing — there's no middle ground for "only in repos belonging to my company."

Proposed Solution

Add a remote condition to rules file YAML frontmatter:

---
remote: "github.com/my-org/*"
---

Matches against configured git remotes using glob patterns. Combinable with existing paths condition.

Medium - Would be very helpful

Use Case Example

I work on company repos and personal repos. My company has coding standards that should apply to all company repos but not personal projects. With a remote condition in ~/.claude/rules/, the right rules activate automatically based on which repo I'm in.
