feat(system): registry glob discovery, drone stderr fix, pyright OOM fix (#38)

Registry discovery (drone, spawn, seedgo) now globs for *_REGISTRY.json
with CWD-first walk-up — enabling project isolation without hardcoded
filenames. Drone stderr crash fixed (Rich Console). Pyright OOM fixed
via pyrightconfig excludes. AIPASS.md simplified for universal use.
Global prompt updated with flow commands. DPLAN-003 added for
AIPass-as-OS design vision.

+# Portability Audit — Session 24 Results
+
+## Summary
+
+| Tool | Registry Discovery | CWD-Aware | Portable | Hardcoded |
+|------|-------------------|-----------|----------|-----------|
+| Drone | Walk-up + env var | No (uses registry) | Yes | Registry filename |
+| Spawn | Walk-up + env var | No (uses registry) | Partial | Template location |
+| Prax | Walk-up (no env) | No (sys logs at repo) | Partial | System logs dir |
+| AI_Mail | Walk-up (no env) | No (inbox per branch) | Yes | Inbox location |
+| Flow | Walk-up (no env) | Yes (plan creation) | Hybrid | Plan registry |
+
+## Key Findings
+
+- All tools use walk-up strategy to find `AIPASS_REGISTRY.json`
+- Registry-relative path resolution already works (move registry + dirs = works)
+- `AIPASS_REGISTRY` env var supported by drone and spawn
+- System logs hardcoded to `{repo_root}/system_logs/`
+- Spawn templates hardcoded to `{spawn_package}/templates/`
+- Walk-up doesn't stop at project boundaries — finds nearest registry up the tree
+
+## The Core Fix
+
+Change `find_registry()` to:
+1. Walk up from CWD looking for `*_REGISTRY.json` (glob, not hardcoded name)
+2. Stop at first match — that's the project boundary
+3. If none found, return error ("No AIPass project. Run `aipass init`")
