chore(qol): Build custom CoPilot instructions from CONTRIBUTING.md:

- Add a script and pre-commit command to generate a CoPilot instructions file  from CONTRIBUTING.md guidelines.
- Add custom instructions for CoPilot to help with influxdb3 placeholders

+## Best Practices
+
+- Use UPPERCASE for placeholders to make them easily identifiable
+- Don't use pronouns in placeholders (e.g., "your", "this")
+- List placeholders in the same order they appear in the code
+- Provide clear descriptions including:
+- - Expected data type or format
+- - Purpose of the value
+- - Any constraints or requirements
+- Mark optional placeholders as "Optional:" in their descriptions
+- Placeholder key descriptions should fit the context of the code snippet
+- Include examples for complex formats
+
+## Writing Placeholder Descriptions
+
+Descriptions should follow consistent patterns:
+
+1. **Admin Authentication tokens**: 
+   - Recommended: "a {{% token-link "admin" %}} for your {{< product-name >}} instance"
+   - Avoid: "your token", "the token", "an authorization token"
+2. **Database resource tokens**:
+   - Recommended: "your {{% token-link "database" %}}"{{% show-in "enterprise" %}} with permissions on the specified database{{% /show-in %}}
+   - Avoid: "your token", "the token", "an authorization token"
+3. **Database names**:
+   - Recommended: "the name of the database to [action]" 
+   - Avoid: "your database", "the database name"
+4. **Conditional content**:
+   - Use `{{% show-in "enterprise" %}}` for content specific to enterprise versions
+   - Example: "your {{% token-link "database" %}}{{% show-in "enterprise" %}} with permission to query the specified database{{% /show-in %}}"
+
+## Common placeholders for InfluxDB 3
+
+- `AUTH_TOKEN`: your {{% token-link %}}
+- `DATABASE_NAME`: the database to use
+- `TABLE_NAME`: Name of the table/measurement to query or write to
+- `NODE_ID`: Node ID for a specific node in a cluster
+- `CLUSTER_ID`: Cluster ID for a specific cluster
+- `HOST`: InfluxDB server hostname or URL
+- `PORT`: InfluxDB server port (typically 8181)
+- `QUERY`: SQL or InfluxQL query string
+- `LINE_PROTOCOL`: Line protocol data for writes
+- `PLUGIN_FILENAME`: Name of plugin file to use
+- `CACHE_NAME`: Name for a new or existing cache
+
+## Hugo shortcodes in Markdown
+
+- `{{% code-placeholders "PLACEHOLDER1|PLACEHOLDER2" %}}`: Use this shortcode to define placeholders in code snippets.
+- `{{% /code-placeholders %}}`: End the shortcode.
+- `{{% code-placeholder-key %}}`: Use this shortcode to define a specific placeholder key.
+- `{{% /code-placeholder-key %}}`: End the specific placeholder key shortcode.
+
+## Language-Specific Placeholder Formatting
+
+- **Bash/Shell**: Use uppercase variables with no quotes or prefix
+  ```bash
+  --database DATABASE_NAME
+  ```
+- Python: Use string literals with quotes
+  ```python
+  database_name='DATABASE_NAME'
+  ```
+- JSON: Use key-value pairs with quotes
+  ```json
+  {
+    "database": "DATABASE_NAME"
+  }
+  ```
+
+## Real-World Examples from Documentation
+
+### InfluxDB CLI Commands
+This pattern appears frequently in CLI documentation:
+
+{{% code-placeholders "DATABASE_NAME|AUTH_TOKEN" %}}
+```bash
+influxdb3 write \
+  --database DATABASE_NAME \
+  --token AUTH_TOKEN \
+  --precision ns
+{{% /code-placeholders %}}
+
+Replace the following placeholders with your values:
+
+{{% code-placeholder-key %}}`DATABASE_NAME`{{% /code-placeholder-key %}}: the name of the database to write to
+{{% code-placeholder-key %}}`AUTH_TOKEN`{{% /code-placeholder-key %}}: your {{% token-link "database" %}}{{% show-in "enterprise" %}} with write permissions on the specified database{{% /show-in %}}
