Add todoObsidian tool for syncing TODOs to Obsidian

Scans codebases for TODO/FIXME/HACK/XXX comments and generates Markdown
notes in an Obsidian vault. Includes Zed editor integration that runs
on file save, plus a shell wrapper for CLI usage. Supports customizable
vault paths, project names, and output directories.

+# todoObsidian
+
+Scan a codebase for `TODO`, `FIXME`, `HACK`, and `XXX` comments and create a Markdown note per project inside your Obsidian vault.
+
+## Installation
+
+No external dependencies (uses the Python 3 standard library).
+
+Make the wrapper executable:
+
+```bash
+chmod +x todo-to-obsidian.sh
+```
+
+## Usage
+
+### Basic
+
+```bash
+python3 main.py /path/to/your/project
+```
+
+### Specify vault path
+
+```bash
+python3 main.py /path/to/your/project --vault ~/Obsidian/MyVault
+```
+
+### Custom project name
+
+```bash
+python3 main.py /path/to/your/project --name "My Awesome App"
+```
+
+### Custom output folder inside vault
+
+```bash
+python3 main.py /path/to/your/project --output-dir "Project TODOs"
+```
+
+### Using the shell wrapper
+
+```bash
+./todo-to-obsidian.sh /path/to/your/project
+```
+
+### Zed integration (run on file-save)
+
+A Zed task is included in `.zed/tasks.json` that automatically scans the workspace and syncs TODOs to Obsidian every time you save a file.
+
+1. Open the `obsidianUtils` folder as a workspace in Zed.
+2. Save any file — the task runs in the background.
+3. Check your Obsidian vault under `Todos/TODOs obsidianUtils.md`.
+
+If the task does not run automatically on save, you can also trigger it manually via **cmd-shift-p → tasks: run task → "Scan TODOs to Obsidian"** (or bind it to a key in your `keymap.json`).
+
+#### Customizing the Zed task
+
+You can edit `.zed/tasks.json` to:
+- Change `--output-dir`
+- Set a custom `--name`
+- Add `--vault` if `OBSIDIAN_VAULT` is not set
+
+Example with explicit vault:
+```json
+{
+  "label": "Scan TODOs to Obsidian",
+  "command": "python3",
+  "args": [
+    "todoObsidian/main.py",
+    "{ZED_WORKTREE_ROOT}",
+    "--vault",
+    "/Users/you/Obsidian/MyVault"
+  ],
+  "tags": ["file-save"],
+  "cwd": "{ZED_WORKTREE_ROOT}",
+  "reveal": "no",
+  "hide": "on_success",
+  "allow_concurrent_runs": false
+}
+```
+
+## Environment Variables
+
+| Variable | Description |
+|----------|-------------|
+| `OBSIDIAN_VAULT` | Path to your Obsidian vault (used if `--vault` is omitted) |
+
+## Supported File Types
+
+- Python, JavaScript, TypeScript, Java, C, C++, Rust, Go, Ruby, Shell, Swift, Kotlin, Scala, R, Lua, PHP, C#, F#, Markdown, YAML, JSON, TOML, INI, and Makefiles/Dockerfiles.
+
+## Output Format
+
+A note is created under `Todos/` in your vault:
+
+```markdown
+# TODOs – ProjectName
+
+_Scanning on 2026-05-26 14:30_
+
+## Summary
+- **TODO**: 3
+- **FIXME**: 1
+
+## By File
+
+### `src/main.py`
+- [ ] **TODO** (line 42) – refactor this function
+- [ ] **FIXME** (line 55) – handle edge case
+
+### `README.md`
+- [ ] **TODO** (line 10) – add installation instructions
+```
+
+## What Gets Skipped
+
+- Hidden directories (`.git`, `.vscode`, etc.)
+- Common build / dependency folders (`node_modules`, `venv`, `target`, `build`, etc.)
