Add a Slack action with Web API functions (post/reply/update/delete messages, reactions, DMs, file upload, channel/user operations), Block Kit builder utils, and five Rest-based Events API triggers with their payload data types and signature verification. Declare the rest-action dependency in the manifest, as every other action with Rest-based events does. Refs #46
The branch was authored before the repo-wide bump to ^1.6.0, so it still pinned ^1.1.1 (resolving to 1.4.5). Match the other node actions; the lockfile now resolves to the latest 1.7.2. Refs #46

What
Adds a Slack action so Hercules flows can post/update/delete messages, reply in threads, react, DM users, upload files, and drive channel/user operations via the Slack Web API — plus five
Rest-based Events API triggers (SlackMessagePosted,SlackAppMentioned,SlackReactionAdded,SlackChannelCreated,SlackSlashCommand) with their payload data types and request-signature verification.Why
Closes #46.
Slack is the canonical "notify a human / capture a human decision" step and one of the most-used integrations on n8n/Zapier, pairing naturally with the e-commerce and comms actions already in the repo.
