fix: add Bash(git init:*) to create-marketplace allowed-tools (#110)

## Description

Adds the missing `Bash(git init:*)` tool to the `create-marketplace`
command's allowed-tools frontmatter. This tool was referenced in Phase
4's instruction to "Initialize git repo if creating new directory" but
was not authorized in the frontmatter.

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] Documentation update (improvements to README, CLAUDE.md, or
component docs)
- [ ] Refactoring (code change that neither fixes a bug nor adds a
feature)
- [ ] Configuration change (changes to .markdownlint.json, plugin.json,
etc.)

## Component(s) Affected

- [x] Commands (`/plugin-dev:*`)
- [ ] Skills (methodology and best practices)
- [ ] Agents (requirements-assistant)
- [ ] Hooks (UserPromptSubmit)
- [ ] Documentation (README.md, CLAUDE.md, SECURITY.md)
- [ ] Configuration (.markdownlint.json, plugin.json, marketplace.json)
- [ ] Issue/PR templates
- [ ] Other (please specify):

## Motivation and Context

The `create-marketplace` command instructs Claude to initialize a git
repository in Phase 4, but the `Bash(git init:*)` tool was not included
in `allowed-tools`. This caused the command to either fail or prompt for
additional permissions, breaking the guided workflow.

This was discovered during a comprehensive review of both plugin
commands against Claude Code plugin command best practices and official
documentation.

Fixes #109

## How Has This Been Tested?

**Test Configuration**:
- Verified YAML frontmatter syntax is valid
- Ran markdownlint with no errors
- Compared with create-plugin.md which correctly includes this tool

**Test Steps**:
1. Ran `markdownlint plugins/plugin-dev/commands/create-marketplace.md`
- passed
2. Verified frontmatter structure matches create-plugin.md pattern
3. Confirmed `Bash(git init:*)` is placed after `Bash(mkdir:*)` for
logical grouping

- [x] Error handling is included for common failure modes
- [x] GitHub CLI commands are properly formatted
- [x] Success/failure messages are clear and helpful

### Testing

plugins/plugin-dev`
- [x] I have tested the full workflow (if applicable)
- [x] I have verified GitHub CLI integration works (if applicable)
- [ ] I have tested in a clean repository (not my development repo)

### Version Management (if applicable)

- [ ] I have updated version numbers in both `plugin.json` and
`marketplace.json` (if this is a release)
- [ ] I have updated CHANGELOG.md with relevant changes

## Additional Notes

This is a one-line fix that aligns `create-marketplace.md` with
`create-plugin.md`, which correctly includes `Bash(git init:*)` in its
allowed-tools.

**Before:**
```yaml
allowed-tools: Read, Write, Edit, Grep, Glob, Bash(mkdir:*), TodoWrite, AskUserQuestion, Skill, Task
```

**After:**
```yaml
allowed-tools: Read, Write, Edit, Grep, Glob, Bash(mkdir:*), Bash(git init:*), TodoWrite, AskUserQuestion, Skill, Task
```
