🎉 release v0.10.5 (#435)

* 🎉 release v0.10.5

* 📝 Remove '(Not Released)' from Health Check heading in README

* 💬 Add Slack bot token support (alternative to webhooks)

Support Slack App bot tokens (xoxb-...) with channel-based posting
as an alternative to incoming webhook URLs.

Config:
  alert.slack:
    token: xoxb-...      # bot token
    channel: #alerts      # required with token

Existing webhook config continues to work unchanged:
  alert.slack:
    webhook: https://hooks.slack.com/...

Uses slack-go/slack PostMessage API for token mode,
PostWebhook for webhook mode. Both produce identical
message block formatting.
