feat: 回复工具执行时注入更多上下文字段，修复 cron 格式，增强 Skill 导入冲突策略

[AQing-527]

This pull request introduces several improvements and bug fixes across the codebase. The most significant changes are in the skill package import logic, which now supports conflict resolution strategies, and in the reply tool extensions, which enhance metadata handling and test coverage. Additionally, there are minor updates to cron expression documentation and version bumps for multiple modules.

Skill Package Import Conflict Handling:

• Added a new enum SkillImportConflictStrategy to specify how to handle conflicts when importing skills with the same name (options: REPLACE or KEEP_BOTH). If no strategy is provided and a conflict is detected, the import returns conflict info without saving, allowing the frontend to prompt the user. [1] [2] [3] [4] [5]
• Updated SkillExchangeController and InMemorySkillExchangeService to support the new conflict strategy parameter and logic, including improved preview behavior and more robust detection of existing skills by name. [1] [2] [3] [4] [5]

Reply Tool Extensions and Metadata Handling:

• Enhanced BaseReplyCodeactTool to define constants for metadata keys and to copy additional channel metadata (like channel_type and channel_id) into the execution context extensions, improving support for channel-specific reply tools. [1] [2]
• Added a unit test (BaseReplyCodeactToolTest) to verify that channel metadata is correctly copied into the execution context extensions.
• Fixed a bug in FastIntentReactHook where user_id was incorrectly set as tenantId; it now correctly sets the userId field.

Documentation and Usability Improvements:

• Improved documentation for cron expressions in SubscribeTriggerCodeactTool, specifying that a 6-field cron format is expected, and updated code examples accordingly. [1] [2] [3]

Dependency Version Updates:

• Bumped the parent version from 0.2.6 to 0.2.7 in all module pom.xml files to reflect the new release. [1] [2] [3] [4] [5] [6]

Pull request overview

This PR improves the assistant agent’s extensibility and UX around skill import by (1) fixing/expanding CodeactTool auto-discovery, (2) adding skill package import conflict-handling with optional replace/keep-both strategies (plus UI prompting), and (3) enhancing reply-tool context propagation and adding tests. It also updates cron expression documentation and bumps module versions to 0.2.7.

Changes:

• Add SkillImportConflictStrategy and extend skill package import APIs to support conflict reporting and optional resolution (REPLACE / KEEP_BOTH), including management-console UI prompting and new tests.
• Enhance reply tools to propagate channel metadata (channel_type, channel_id) into execution context extensions and add a unit test; fix FastIntentReactHook incorrectly mapping user_id to tenantId.
• Fix CodeactTool Spring auto-discovery merge behavior; update cron docs/examples; bump Maven versions to 0.2.7.
