* feat(channels): Channel.Send and MediaSender.SendMedia return delivered message IDs
Change Channel.Send signature from (ctx, msg) error to (ctx, msg) ([]string, error)
and MediaSender.SendMedia similarly, so callers can capture platform message IDs
for threading, reactions, and history annotation.
Adapters that return real IDs: Telegram (per-chunk MessageID), Discord (Message.ID),
Slack Send (ts), QQ (sentMsg.ID), Matrix (EventID). Slack SendMedia returns nil
because UploadFileV2 does not expose the posted message timestamp in its response.
All other adapters return nil IDs.
preSend and sendWithRetry in manager.go updated to propagate ([]string, bool).
README examples updated for both English and Chinese docs.
* style: apply golangci-lint fixes (golines)
* docs: fix Send migration guide — restore old error-only signature in before/after example
- Add separate User and RealName config fields (fall back to Nick)
- Make RequestCaps configurable (defaults to server-time, message-tags)
- Refactor isBotMentioned into nickMentionedAt returning position;
stripBotMention now uses nickMentionedAt internally
- Replace custom isAlphanumeric with unicode.IsLetter/unicode.IsDigit
- Update tests for new nickMentionedAt function
Sort irc import alphabetically in helpers.go and fix struct field
alignment in irc.go to satisfy golangci-lint gci formatter.
