* feat: allow custom docs folder path via docsDir config

Add a docsDir option to .ai-devkit.json that allows users to
customize where AI documentation is stored instead of the hardcoded
docs/ai path. The init command now prompts for the docs directory,
and templates also support the new field.

Closes #31

* Add --docs-dir CLI flag to init command

Allows setting custom docs directory non-interactively via
`ai-devkit init --docs-dir .ai-docs`. Priority: CLI flag >
template config > interactive prompt > default (docs/ai).

* fix: replace hardcoded docs/ai in command templates with custom docsDir

When copying command templates, replace all `docs/ai` references with
the configured docsDir value. This affects copyCommands, copyGeminiSpecificFiles,
and copyCommandsToGlobal. Also fix init command to use docsDir-aware
template manager for environment setup.

* refactor: address PR review feedback for custom docs dir

- Rename config field from flat `docsDir` to namespaced `paths.docs`
- Change TemplateManager constructor to options object pattern
- Use {{docsDir}} template variables instead of naive string replacement
- Separate docsDir from LintOptions into standalone parameter
- Remove interactive prompt for docsDir during init
- Remove redundant DOCS_DIR constant re-export

* refactor: remove docsDir from InitTemplateConfig, use paths.docs only

Since the feature hasn't shipped yet, there's no need for backward
compatibility with docsDir in templates. This eliminates the dual-schema
confusion and simplifies the fallback chain.

* test: remove redundant docsDir unknown field test

The existing 'throws when unknown field exists' test already covers
this code path.
