refactor: convert plugin tools to skills/ directory structure

Replace "tools" shell script declarations with proper skills/ directory
so Claude Code injects them into system-reminder and Skill tool can invoke them.

Each tool now has its own skills/<name>/SKILL.md with usage prompt.
Remove "type" and "tools" fields from plugin manifests.
Bump version to 1.0.3.

+Analyze the Fission configuration of a project by running the analyze-config script.
+
+## Usage
+
+```bash
+./fission-python/analyze-config.sh <project-path>
+```
+
+- `project-path`: Path to the Fission Python project directory
+
+Requires `jq` to be installed for JSON parsing.
+
+## What it does
+
+Reads `.fission/deployment.json` (and override files) and outputs:
+- Environments defined
+- Packages and their build commands
+- Functions and their configurations
+- HTTP triggers and URLs
+- Cron triggers
+- Secrets and configmaps
+
+## Example
+
+User asks: "Analyze the Fission config of ./my-api"
+
+```bash
+./fission-python/analyze-config.sh ./my-api
+```

+Create a new Fission Python project by running the create-project script.
+
+## Usage
+
+Run the following command from the repository root:
+
+```bash
+./fission-python/create-project.sh <project-name> [destination-directory]
+```
+
+- `project-name`: Name for the new project (letters, numbers, hyphens, underscores only)
+- `destination-directory`: Where to create the project (default: current directory)
+
+## What it does
+
+1. Copies the template from `fission-python/template/`
+2. Substitutes project name in `.fission/deployment.json`, override files, `src/helpers.py`, and `README.md`
+3. Validates the created project structure (build.sh, requirements.txt, workflows, docstrings)
+4. Creates a `.env` file with default environment variables
+
+## Example
+
+User asks: "Create a new Fission project called my-api in ./projects/"

+```bash
+./fission-python/create-project.sh my-api ./projects/

+View or update Fission configuration in a Python function docstring using the update-docstring script.
+
+## Usage
+
+```bash
+# View current config
+./fission-python/update-docstring.sh <file.py> <function-name> --get
+
+# Update config
+./fission-python/update-docstring.sh <file.py> <function-name> --set '<json>'
+```
+
+## Docstring format
+
+The script reads/writes Fission config between ` ```fission ` and ` ``` ` markers:
+
+```python
+def main():
+    """
+    ```fission
+    {
+        "name": "function-name",

+    ```
+    """

+
+## Examples
+
+User asks: "Show the Fission config of function `main` in `./my-api/src/func.py`"
+
+```bash
+./fission-python/update-docstring.sh ./my-api/src/func.py main --get
