## Summary
- Fixes a compile error in `internal/channels/qqbot.go`: the local
`stringValue(value any)` helper collided with the existing
`stringValue(value *string)` in `feishu.go` within the same package
(`stringValue redeclared in this block`).
- Rename the qqbot variant to `anyToString` (definition + 13 call
sites). The two helpers do different jobs (any->string via `fmt.Sprint`
vs. `*string` deref), so they are not merged.
