Add Effect submodules and TypeScript work rule

TASK-038: Unblock TypeScript research work

- Add .refs/effect (Effect-TS core library reference)
- Add .refs/effect-smol (Effect-TS smol variant reference)
- Add effect-native/ work submodule at repo root
- Update AGENTS.md with TypeScript Work Rule section
  - All TS work happens in effect-native/ submodule
  - Follow spec-first workflow in effect-native/.specs/AGENTS.md

This unblocks TASK-031, TASK-032 and future TS research work.

+# TASK-038: Add Effect submodules + TS-work rule (unblock TypeScript)
+
+## Status
+- [ ] Planned
+- [ ] Assigned
+- [ ] In Progress
+- [ ] Blocked (reason: ...)
+- [x] Complete
+
+## Priority
+high
+
+## Assigned To
+subagent (general)
+
+## Parent Docs / Cross-links
+- Wish: `.wishes/effect-native.md`
+- Repo submodules file: `.gitmodules`
+- Agent rules: `AGENTS.md`
+
+## Description
+Add the submodules required for TypeScript work and codify the rule that **all TS work lives in the `effect-native/` submodule**, following the spec-first workflow defined by `effect-native/.specs/AGENTS.md`.
+
+Submodules to add:
+- References:
+  - `[email protected]:Effect-TS/effect.git`
+  - `[email protected]:Effect-TS/effect-smol.git`
+- Work:
+  - `[email protected]:effect-native/effect-native.git`
+
+Then update `AGENTS.md` with a clear rule:
+- TypeScript work happens only in `effect-native/`
+- For TS changes, agents must read and follow `effect-native/.specs/AGENTS.md`
+
+## Files to Modify
+- `.gitmodules`
+- `AGENTS.md`
+- (new directories created by git submodule add)
+
+## Acceptance Criteria
+- [x] `git submodule status` shows all three submodules present.
+- [x] `AGENTS.md` documents the TS-work rule and points at `effect-native/.specs/AGENTS.md`.
+- [x] Existing non-TS tasks remain valid (no churn).
+
+## Progress Log
+### 2025-12-14
+- Task created from `.wishes/effect-native.md`
+- Subagent began work: marked In Progress
+- Added `.refs/effect` submodule
+- Added `.refs/effect-smol` submodule
+- Added `effect-native` submodule
+- Updated `AGENTS.md` with TypeScript Work Rule section
+- Verified all acceptance criteria met
+- Task complete
+
+## Completion Notes
+### 2025-12-14
+- Added three git submodules:
+  - `.refs/effect` (Effect-TS/effect @ fb78c4061cec89718c49f842a91263a9bb8cf3cf)
+  - `.refs/effect-smol` (Effect-TS/effect-smol @ e0e47d38139e9f182908dc6f26125d59ad0f1219)
+  - `effect-native` (effect-native/effect-native @ 9f6ce02ea21e81110df4ebd2c80f863fdc0173fb)
+- Updated `AGENTS.md` with new "TypeScript Work Rule" section directing all TS work to `effect-native/` submodule
+- Verified `effect-native/.specs/AGENTS.md` exists for spec-first workflow reference

+## TypeScript Work Rule
+
+**All TypeScript work happens in the `effect-native/` submodule.**
+
+When working on TypeScript code:
+1. Navigate to `effect-native/` directory
+2. Follow the spec-first workflow defined in `effect-native/.specs/AGENTS.md`
+3. Use the patterns and conventions documented in `effect-native/AGENTS.md`
+
+Reference submodules for Effect ecosystem:
+- `.refs/effect` — Effect-TS core library
+- `.refs/effect-smol` — Effect-TS smol variant

 This project is undergoing a major rewrite from C/Rust to Zig. The following workflow governs how work proceeds.
