feat: add torch-lock remove command for complete TORCH uninstallation

Users who installed TORCH via `npm install <tarball> && npx torch-lock init`
had no built-in way to cleanly remove it. This adds a `remove` command that
detects and removes all TORCH artifacts: the torch/ directory, config files,
runtime directories (.torch/, .scheduler-memory/, task-logs/), governance
proposals, host package.json scripts, and the npm package itself.

- Add cmdRemove() in src/ops.mjs with detection, preview, confirmation, and cleanup
- Wire up `remove` command in CLI dispatcher (src/lib.mjs)
- Add TORCH_HOST_SCRIPTS constant in constants.mjs for shared script key list
- Add docs/removal.md with full manual removal instructions
- Add removal section to README.md
- Add 7 scenario tests in test/ops-remove.test.mjs

+# Removing TORCH from a Project
+
+This guide covers how to completely remove TORCH from a project repository that installed it via the standard installation process (`npm install <torch-tarball> && npx torch-lock init`).
+
+## Quick Removal (Recommended)
+
+Run the built-in removal command from your project root:
+
+```bash
+npx torch-lock remove
+```
+
+This will:
+
+1. Detect your TORCH installation (whether installed to `torch/` or to the project root)
+2. Show a list of all artifacts that will be removed
+3. Ask for confirmation before deleting anything
+4. Remove all TORCH files, directories, configuration, and the npm package
+
+To skip the confirmation prompt:
+
+```bash
+npx torch-lock remove --force
+```
+
+## What Gets Removed
+
+The `remove` command cleans up everything that `torch-lock init` created, plus any runtime artifacts:
+
+| Artifact | Description |
+|---|---|
+| `torch/` | The main TORCH install directory (contains src, bin, dashboard, scripts, prompts, etc.) |
+| `torch-config.json` | TORCH configuration file at the project root |
+| `.torch/` | Hidden directory for prompt history tracking |
+| `.scheduler-memory/` | Runtime memory store used by the memory subsystem |
+| `task-logs/` | Scheduler run logs (daily/weekly cycle logs, relay health history) |
+| `src/proposals/` | Governance proposals directory |
+| `torch:*` scripts in `package.json` | Convenience scripts injected into the host project's package.json |
+| `node_modules/torch-lock/` | The installed npm package |
+
+## Manual Removal
+
+If you prefer to remove TORCH manually, or if the `remove` command is unavailable (e.g., the package was already uninstalled), follow these steps from your project root:
+
+### 1. Remove the TORCH directory
+
+```bash
+rm -rf torch/
+```
+
+### 2. Remove TORCH configuration
+
+```bash
+rm -f torch-config.json
+```
+
+### 3. Remove hidden directories
+
+```bash
+rm -rf .torch/
+rm -rf .scheduler-memory/
+```
+
+### 4. Remove runtime logs
+
+```bash
+rm -rf task-logs/
+```
+
+### 5. Remove governance proposals (if empty/unused)
+
+```bash
+# Only remove if this directory was created by TORCH and contains no user content
+rm -rf src/proposals/
+# Remove src/ too if it's now empty
+rmdir src/ 2>/dev/null
+```
+
+### 6. Clean up package.json scripts
+
+Remove these keys from the `"scripts"` section of your `package.json`:
+
+```json
+{
+  "torch:dashboard": "...",
+  "torch:check": "...",
+  "torch:lock": "...",
+  "torch:health": "...",
+  "torch:memory:list": "...",
+  "torch:memory:inspect": "..."
+}
+```
+
+### 7. Uninstall the npm package
+
+```bash
+npm uninstall torch-lock
+```
+
+### 8. Clean up environment variables (if set)
+
+If you configured TORCH environment variables in your shell profile, CI, or `.env` files, remove them:
+
+- `NOSTR_LOCK_NAMESPACE`
+- `NOSTR_LOCK_HASHTAG`
+- `NOSTR_LOCK_RELAYS`
+- `NOSTR_LOCK_TTL`
+- `NOSTR_LOCK_QUERY_TIMEOUT_MS`
+- `NOSTR_LOCK_DAILY_ROSTER`
+- `NOSTR_LOCK_WEEKLY_ROSTER`
+- `TORCH_CONFIG_PATH`
+- `TORCH_DASHBOARD_AUTH`
+- `TORCH_MEMORY_ENABLED`
+- `TORCH_MEMORY_INGEST_ENABLED`
+- `TORCH_MEMORY_RETRIEVAL_ENABLED`
+- `TORCH_MEMORY_PRUNE_ENABLED`
+- `AGENT_PLATFORM`
+
+### 9. Optional: Remove generated reports
+
+If you ran lock reliability reports, you may also want to remove:
+
+```bash
+rm -rf artifacts/lock-reliability/
+```
+
+## Verifying Complete Removal
+
+After removal, verify no TORCH artifacts remain:
+
+```bash
+# Should return no results
+ls torch/ 2>/dev/null
+ls .torch/ 2>/dev/null
+ls .scheduler-memory/ 2>/dev/null
+ls torch-config.json 2>/dev/null
+
+# Should not contain torch-lock
+npm ls torch-lock 2>/dev/null
+
+# Should not contain torch:* scripts
+grep '"torch:' package.json
+```
+
+## Re-installing TORCH
+
+If you want to re-install TORCH later:
+
+```bash
+npm install https://github.com/PR0M3TH3AN/TORCH/archive/refs/heads/main.tar.gz && npx torch-lock init
+```
